Review & Install Video
Hey, everybody. I'm Justin with Americanmuscle.com and this is my detailed review, dyno test, and drive of the MPT X4SF4 Power Flash Tuner loaded with three custom MPT tunes available for your 2015 and newer 5.0L F-150. You should be checking out the MPT X4 Combo if you're looking for more than just some canned or preloaded tune and want a premium experience that you often times get with a custom tune. Now, this is gonna allow you to get more out of your truck from towing, to performance, to fuel economy, with all of its current modifications along with future modifications, thanks to MPT's free tune revisions.
Now guys, the MPT tune will cost you a little bit more initially but hopefully by the end of this video, you'll know why this is money well spent. In this video, I'm gonna talk to you about why you might wanna go with the MPT tuned X4 device over some of your other options here at americanmuscle.com. We're gonna talk about the power improvements over stock, the fuel economy benefits, and of course, the drivability improvements, including shifting and throttle response. So hang out with me, guys. I've got a lot to talk about here. We're gonna walk you through the device. We're actually gonna hop in the truck and go for a spin later on in the MPT tune 5.0L. But first, let's talk about what kind of power numbers you can expect using this combo.
Now, before you even strap the truck to the dyno, we replace the big heavy aftermarket 35s in the rear with the factory wheel and tire setup just for the most accurate results on our dyno jet. We then proceeded to knock out those baseline runs using 87 octane. Finally guys, we drained that 87 octane, filled it up with some 93 octane, uploaded the corresponding tune from MPT and here are those results. Our baseline run using our 2015 5.0L F-150 gave us 278 horsepower and 316 pound-feet of torque at the rear wheels. With our 93 octane PRX tune uploaded, the truck made 293 horsepower and 340 pound-feet of torque. We gained 15 horsepower and 24 pound-feet of torque peak along with 30 horsepower and 27 pound-feet of torque under the curve.
All right guys, breaking down the graph a little bit here at the MPT custom tunes, now the 93 octane PRX tune made a ton of power all over the place here. I felt this driving the truck all week long. The truck just felt very, very healthy and these are some of the biggest gains we've seen out of any of the truck tuners available here at americanmuscle.com. Now, this is pretty obvious because a 93 octane tune usually allows more of ignition timing, a slightly more aggressive tune, things like that and that's why you're gonna see these bigger numbers. They do offer you some different options, including their towing, economy, and race tunes available for each different octane level. So again, as you can see, the tunes are definitely doing their job. So what do you say we get up to the table and break down the tuner a little further?
In addition to the different engine calibrations, MPT also gives you the option of going with their transmission tunes or tweaks or leaving the transmission untouched if you're happy with how it shifts in factory form. Now, this pretty cool to get this option, but take my word for it guys, go with the full treatment. MPT's transmission tweaks are totally awesome and I'm gonna touch on more of those later on when we go for a spin.
Speaking of driving, guys, I've been pounding the pavement all week long here with our MPT tune 5.0L F-150 just to get a better sense of what this thing is all about and also to see how our fuel economy fared. Now, full disclosure, all the tunes I tested improved miles per gallon somewhat over the factory calibration, whether it'd be MPT, SCT, Edge, or Superchips. Now in my experience, I found the MPT custom tune to land somewhere right in the middle between the SCT preloads and the Edge and Superchips preloads. Now, as far as my driving route, guys, well, I see a healthy mix of both highway and backroads and with the factory calibration on 87 octane, I was seeing anywhere from 11 to 12 miles per gallon with our lifted rig on 35s and a rather heavy foot.
Now with the 93 octane performance economy tune from MPT, I was seeing anywhere from 13 to 13 ½, even 14 miles per gallon using the same route and driving style. Now, I do wanna quickly point out guys that all of MPT's performance tunes essentially make the same amount of power at wide open throttle using the same octane. For instance, the performance economy, performance extreme, which is essentially the race tune, and the performance towing. The changes are gonna come when you're looking at the part throttle cruising. For instance, the performance economy tune is going to use a very tame calibration when off the throttle or when you're looking at part throttle cruising and is essentially gonna shift you into those higher gears faster to get you the best fuel economy possible. So you're gonna looking at the best of both worlds here, guys, fuel economy when you want it but the power is gonna be on tap when you need it to pass or merge onto the highway.
Switching gears price guys, I think you're gonna find the MPT loaded X4 to be pretty good at just north of 400 bucks, which isn't too shabby considering you're getting a solid tuning option here, a custom tune at that, along with a pretty capable device in the X4. Now, because this is a custom tune, you're gonna have the ability to add those different modifications such as your intakes, your exhaust, your long tube headers and even intake manifolds along with getting the additional tune revisions at no additional charge from MPT as long as you don't add forced induction or something a little bit more involved. So now that you know what you guys are getting with the custom MPT tune, let's hop in the truck, we'll plug in the X4, and then we'll go for a spin.
All right, guys, so we're out in our 2015 5.0L F-150. I have the MPT 93 octane PRX tune installed or uploaded. It's my favorite tune. It's the one I want to drive again. I did drive some of their other tunes but out of all the tunes I tested, the MPT tunes were by far and away my favorite tunes for the 5.0L truck. They offer the biggest gains, the biggest difference in drivability, and the power is just...I mean you get on this thing, it's heavy. It's got the 35, they're lifted six inches. The transmission settings are simply out of this world and I think that's probably one of my favorite things about the tunes themselves. Just leaving a red light, the truck will get you in a second instantly and then it just puts you right in the power band. So no matter where you are on the road, if you're on the highway, if you're on the backroads, just the slightest input in throttle will get you to downshift the gear, just like I did there. I mean I didn't have to really give a half throttle, three-quarter throttle and the truck reacted.
No. I gave it the smallest input and the throttle response is probably some of the best I've driven here with a 5.0L truck. Now, some of you guys might like that. Some of you guys might like a truck that shifts a lot because it's always putting you in the power band. On the other hand, some of you guys might not. And if that's the case, again, MPT does give you that option. You can leave all your stock transmission settings pretty much the same. You can leave the factory transmission calibration in the truck or go with more of their power stuff and that's totally an option. You can definitely do that. But again, take my advice, I've driven a lot of these tunes and the transmission settings from the factory with these 5.0L trucks or with any of the F-150s for that matter are just a little soft and leave a lot to be desired. Especially when you're on the highway and you wanna downshift or you wanna pass, you know you basically gotta put this thing to the floor to get it to do anything. Not the case with MPT.
Again, you give it a half throttle and there we go. We're down two gears already and we're moving along pretty quickly. So again, huge gains in both torque and horsepower, the biggest we saw out of all the tunes we tested here at AM for the 5.0L to this day. And it's really to no surprise, right? Custom tunes, they're just gonna be a better, more refined product. You're gonna see bigger gains because you're getting a tune essentially custom-tailored for your ride. But even with this, even with their stock truck essentially, just with the lift and everything, we still saw again the biggest gains in horsepower and torque, the biggest curve gains. So if you're towing, you know, or if you just like beating on your truck occasionally, the MPT is gonna offer you the best bang for your buck. Now sure, they're gonna be a little bit more essentially when it comes to the overall price tag depending on your device, but you're getting a better product, guys. That's the really only way I can put it. I've gotta be blunt about it. Sure, the preloads are nice but overall, for a little bit extra, you're getting a lot more of a product, and I really can't stress that enough, when going with a custom tune.
For a big old heavy truck, it definitely gets out of its own way now with the MPT tunes. And even with the economy tune, even with the towing tune, again, I told you guys in the overview, wide open throttle using the same octane, the truck is gonna make the same number. Basically, wide-open throttle, the dyno result, the power is all gonna be there. However, the PRX tune, it just yields more sporty, not granted. I drive a Mustang once in a while too, so maybe that's why I'm such a fan of the PRX tune. But personally, if I were to drive this thing every day, I'd probably leave it in the economy tune, the performance economy tune, because you're getting the best miles per gallon when it comes to all of their tunes but you're also getting the power when you want it. From the performance, down to the drivability, down to the transmission settings, I really love these things. I can't say enough good stuff about them, as you can tell.
Let's head back to the shop and I'll walk you through the actual SET X4 itself. And I'll think you'll find the SET, it's gonna be one of your most popular devices in the tuning aftermarket. The X4 is definitely one of the most user-friendly devices, at least in my experience. I'm gonna walk you through her right now. We'll start with the gauges and data logging. I think this is gonna be probably the most popular feature with the X4. It's something a lot of you guys are gonna use the most, I think, when having this thing in your rig. You're starting off with two pieces of data here now, your intake air temperature and your control module voltage. Now, this is only one of many layouts with the X4. We'll get into it a little bit here. We can actually go ahead and select our gauge layout and I have a number of different layouts to choose from with the X4. So two is what they start you off with but you can go all the way down to eight here at one time to be displayed on the screen. We'll run down through some of them right now.
We're starting with boost to get an EcoBoost. That would probably be a very useful one. The voltage, cooling temp, intake air temperature, you know, fuel trims, things like that. We have all kinds of stuff here. Air fuel ratio, which is a big one with the SET. A ton of different stuff to choose from with the X4 and have it all be displayed here for you. So you can go through the menu. You can actually choose a horizontal or landscape mode and have it be displayed sideways, if you prefer. Personally, I like using it in the vertical mode and I found that you can buy the suction cup mount if you want but I actually have a holder for my iPhone. It works perfectly in there. Not a bad idea for you guys.
Now, if you wanna actually data log this stuff, if you're, like I said, making a wide-open throttle pool, if you wanna review some data logs, see what the truck is doing, very, very easy to do. You're gonna wanna setup all the stuff you wanna data log and when it comes time to record it, all you do is simply hit that middle button there. You can see the record button flashes up, you let it go as long as you want and you can basically stop it at any point hitting the center button again. So and this is something that you probably wanna offload onto your computer to be reviewed by your tuner or by yourself if you're into that sort of thing. So go down one to your vehicle functions, this is your diagnostic tool with the X4. This is gonna be where you read and clear diagnostic trouble codes, or your check engine lights better known as. We have no codes currently, but if you did, it would display the code in its identifier basically starting with a P or something like that and it would actually expand upon what it is. So if you had a misfire code or something like that, it would tell you on here. And you can actually clear the codes too if you wanted. Go down one, clearing your codes, all of our codes all cleared. So there you go.
Go down one more, this is your special vehicle functions. You can do a cam reset, which is your keep alive memory basically stored into the ECU. Basically, this gets cleared every time you disconnect your battery anyway or your crank relearn if you happen to have a misfire code or something like that, you'd get into that. So again, very useful things to have here on the X4. But on the vehicle info, you can view your VIN here, your strategy code, which is what you're gonna need to look at once in a while when communicating with your tuner, ECU, all that good stuff there. Now, a nice thing about the X4, this thing has built-in wireless, so if you do need to update your firmware, which is something you need to do with tuners frequently, they often times send out updates. You don't need to plug this thing and then update it. It's wireless, so as long as it hooks up into your Wi-Fi, the X4 will download the necessary firmware updates for you automatically and it's a very useful feature to have.
So here is a display orientation I talked about. We can change the landscape if you want. So now there you see. We can turn it sideways and then you can do more of a landscape setting if that's what you're into. We'll change that back to portrait real quick. Light sensor, this is again, this is your light sensor. You can actually see it right here. It's built-in. So it'll just dim, it if you like, automatically. We have that set up already on ours. So it detects automatically when it's dark out. It dims at 4:00. It's pretty nice. Power management mode, that way it won't kill your battery. Basically, you can leave this thing plugged in at all times. You leave it on auto here, it'll basically power down after being inactive for a few minutes. If you leave it always on, it's gonna drain your battery. So just leave it on auto and you should be good to go there. This is pretty cool as well, startup. You can either have it start up any time you plug it in or turn your truck on. It'll default to the main menu. Or what I do is when I have the X4 in my truck, I have it start automatically to the gauges because that's where you usually end up anyway. So that's pretty cool. They give you that option. And then your factory reset, this is just gonna reset the gauges.
All right guys, with most of the X4 pretty much gone over by now, let's get into the program vehicle operation here, very simple stuff. Again, click on the program vehicle tab, make sure your key is in the on position, which we already have, so we're good to go there. And then it's gonna bring you to the tunes you wish to upload. Now, we have some preloaded tunes on there but we also have our MPT custom tunes, 93 octane performance tow and our PRX. So from here on out guys, you're basically just following the on-screen instructions when uploading your tune, very, very easy stuff. Now, it's gonna bring you to this screen as well. This gives you some additional options and this is really cool because, yes, even though the MPT tune is a custom tune, they still give you the options to changing your tire size, your axle ratio, things like that.
So for us, for instance, we have a 35 on this thing. We're just gonna scroll down the list here, select 35 from the SET tuner. There we go. Now, our speedometer and everything should be completely accurate. It also gives you the opportunity to switch up your rev limiter, speed limiter, things like that. SO if you wanna lend your truck to somebody of if you wanna you're your son or daughter borrow it for a little bit, you can kind of put on some nanny features for them as well. So we're pretty much good to go here. So we are gonna all go ahead and hit approve and from here on out, we are pretty much ready to rock N roll. So the tune is gonna flash. This should take you a few minutes, very easy stuff, guys. I know I said that already but I will say it again. One out of three wrenches on my difficulty meter in regards to overall install difficulty. I mean you're basically just hitting a few buttons here. It should take you no longer than 15 to 20 minutes the first time and then flashing the truck becomes a little faster after that.
All right guys, so that's my detailed review of the MPT custom tunes loaded on the SET X4 device. Be sure to learn more about the device and the tunes right here at americanmuscle.com.
