    Review & Install Video

    Hey everybody, Justin with here with my review and Dyno test of the VMP SF4 X4 Flash tuner, loaded with three custom VMP tunes, available for your 2015 and up Mustang GT. Now the VMP option is definitely going to be a top tier tune option here at AM, and I think a good way to describe it would be a more refined product overall. It's really going to shine with those heavily modded full bolt-on setups, nitrous cars, and especially forced induction setups, and that's where VMP really earn their reputation. Now, with all that said, can you use this on a stock or a light bolt-on car? Absolutely. In fact, I would definitely say it's a solid option for you guys at home who know the VMP name and don't mind spending a few bucks extra compared to some other tune options here on the site. So why is the VMP going to be a top tier tune option here at AM? Well, they have been around in the tuning industry for quite some time now, and over that time they've of course developed their power, as we'll show you, on the Dynojet here in a little bit. But also during that time, they've really done their homework and dialed in great drivability. I think that's going to be the biggest separating factor when going with the VMP tune. It's a more refined product again. What does this mean for you? While driving the car around town, no idling issues, no surging issues, smooth throttle response. It's not going to be stalling out, things like that. And after driving the car myself I can attest to all these things. Again, around town the car idles and drives like a factory Mustang, but once you start laying into the throttle a little bit you can really feel the increased throttle response and the increased power throughout the RPM range. Now, as I mentioned at the top of this video guys, you are getting three tunes written by VMP ordered through us here at AM, a low, medium and high octane tune depending on what kind of fuel you have in your area. Now that lower octane tune, again you're going to see some benefits over your factory calibration, a little bit more power of course, definitely that improved drivability that I talked about a little earlier. But, it's not going to be as aggressive as their high octane tune which typically does utilize a little bit more timing and some other stuff to get you those bigger power gains. Also worth pointing out here guys, VMP does offer one data log revision with their tunes if necessary. As I mentioned at the top of this video again guys, you are getting a premium product here with the VMP tune and it is going to cost you a little bit more right off the bat. They do offer those slightly more in depth tunes such as your E85 tune, some nitrous applications, and even those forced induction tunes, but they will add a little bit more to the price tag when ordering. Also don't forget guys, these tunes are coming loaded on the SF4 X4 Power Flash tuner here which does have some nice notable features as well. Some of the biggies with the device do include the full data logging capabilities, nice bright full color LCD screen, the ability to read and display up to eight different values of your car at one time including RPM, intake air temperature, air fuel ratio boostings like that. It can hold up to 10 tunes at one time and it can read and clear those diagnostic trouble codes. When it does come time to upload your custom VMP tune, I think you'll find it's going to be one of the easier mods you're ever going to do to your new Mustang. We call it one out of three wrenches on the difficulty meter, but honestly I think that's being a little generous. First, you're going to locate your car's OBDII port. On the 2015 and up Mustangs, it's located on the lower left hand portion of the dash on the driver's side. Plug the tuner in and wait for it to power on. Navigate the menus, find the program vehicle tab and go ahead and select the tune you wish to upload. Follow the directions on the screen and you should be good to go in a few minutes from start to finish. We already ran our 2015 manual GT on our Dynojet behind me, established some baseline numbers and then we re-ran the car with the 93 octane VMP tune uploaded. Here's how the VMP tune performed. Baseline we're looking at 386 horsepower, 364 pound-feet of torque at the rear wheels. With the 93 octane VMP tune uploaded, the car is now making 402 horsepower, 375 pound-feet of torque, making for a peak gain of 16 horsepower over those baseline numbers and gains of as much as 24 horsepower, 24 pound-feet of torque under the curve. Breaking down the numbers a little bit guys, here's what I notice. These peak numbers are nice and all, but the big story with the VMP tune is the numbers underneath the curve, the gains underneath the curve. For instance, you're picking up a ton of torque down low in between 2,000 to 4,000 RPM, and you're picking up a bunch of power up high when it comes to horsepower. That low end torque, that's what you're going to feel red light to red light, merging onto the highway, things like that. On the flip side, that high end power is what you're going to feel when you really start winding out the car a little bit, getting into those upper RPM ranges and hitting the drag strip, things like that. Overall my final impressions of the tune driving the car, it pretty much mirrors the Dyno graph. I mean, I felt like the car was a little healthier down low and at the same time it really did come to life over 5,000 rpm. With the VMP tune, sure, you're paying a little bit more for it up front, but you're getting an established name that can pretty much handle anything from your bone stock or lightly modded GT all the way down to your big boost forced induction setup.

    Get Your Money's Worth. From the factory, Ford programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. That is why a custom tune file is so important, by optimizing the air/fuel ratio, adjusting ignition timing and tweaking variable cam timing, a VMP Tuning Custom Tune will squeeze out the extra power your aftermarket performance mods have to offer.

    VMP Custom Tunes. When you order a custom tune from VMP Tuning they are written specifically for your personal Mustang and your particular modifications with your choice of octane level. VMP Tuning even provides one post sale datalog review (if necessary) to assure your Pony is running healthy and strong.

    Compatible with the following tuning devices (not included):

        I have a 2015 GT with cai and borla catback and I want to add a 2018 intake manifold to it. I have bama tune and the sct tuner already. Will this custom tune work with the 2018 manifold? Thanks.

        • Yes, that application would indeed qualify as for VMP's tune for bolt on modifications.

        Is a ported 2018 manifold bolt on?

        • That would not be considered a basic bolt-on modification.

        I bought a 2017 Mustang Premium GT/CS (24k miles) that looks like it had the nGuage in the center air vent. the vent was replaced but the cable is still there, I unplugged the cable at the port. I want to tune with the VMP 1 Stock Tune cause I'm not sure of the nGauge settings. Can the VMP override the existing tune ok? Would there be any problems doing so if I installed VMP under this condition?

        • The VMP tunes will work as desired, but they will save the existing tune as the "stock" tune. The only effect this will have is that you will not have a stock tune.

            GT350 Cold Air with Stock Throttle Body

            Picked up a GT350 Cold Air Kit and needed a tune! I didn't want to change the stock 80mm throttle body out. VMP was first choice due to ordering tunes in the past. It was as simple as pay, fill out required information and wait a few days and boom. Loaded it up and the first drive up the street was SUPER HEALTHY! The first 3 gears pulled extremely hard. VMP has a customer for life! SUPER EASY TO DO! Thank you VMP and American Muscle.

            They do not do catless tunes

            I bought BBK catless longtubes along with the tune after waiting a week and a half I called to ask about my tune and that’s when I was informed that they do not do catless tunes. I wished they would have informed me of that before hand. I ended up getting a tune from Lund and I am very impressed with their service.

            Nice gains

            Great tune. Easy to download and transfer to tuner. VMP contactes me rights away to confirm a few things after that they had my tune ready in no time. Still gotta get my car dyno to see the real numbers.

            Great Tuning Company and Fantastic Tune

            This tune increased the throttle feel and overall driveability of my Mustang. Loads on real quick and VMP sent the tune over quickly. I put in the wrong serial number when I ordered the tune, and they still corrected the same day and sent it back to me.

            Awesome upgrade

            Throttle response and everything over all is an amazing difference. Lost a little of my mpg average but that might be because I love mashing the throttle now! Couldn't be happier with this purchase.

            custom over cai tune

            Would have to do a dyno test on both tunes, to see the difference! Honestly I can't tell if the difference was worth it!
