        The "pro calibration tool" is a tuner correct? If so, would this tuner work for other mods i.e cold air intake, intake manifold? Thank you!

        • The pro-calibration tool is a tuner and can be tuned for other Ford Performance modifications along with the size of the wheels and tires you have.

        Does this have the lope tune like the track cal?

        • That is not a function that intrinsically comes with this kit, no. A ghost cam tune, like you are referring to, must be a custom tune requested directly. You would need to speak with Ford directly upon what they can and cannot offer in terms of additional custom tuning.

        Extra Torque??? So I see a Ford Racing power pack with the procal tuner and air filter (the only difference between the two packages are the axelbacks) and I am wondering what is adding the additional torque? HP appears to be the same at "up 16" but the torque is drastically different at +60 versus +7 for the other kit. Does anyone have a good answer on where it's coming from because right now it seems too good to be true? I haven't read anywhere where axelbacks have increased output that much... Any clarity is helpful! Thanks! 1 answer

            A must have for a 11 - 14 Mustang Owner

            After 6 years I finally picked up and installed this kit on my 2013 GT Trakpac. Except for the minor damage to the exhaust tips everything was good. Package arrived in about 4 days and another 3 for the procal. I installed the kit using a floor jack and stands. It worked but I could have used about 4 or 6 inches more lift. Between the mufflers and the tune it took about 4 hours, could have been faster but determining the socket size and the best way to remove the old exhaust used up some time. The sound is perfect, bit more throaty but no drone on hwy. Just a note if you get this kit on install. The factory clamp is 1/2 inch but the GT500 clamp is 9/16 bold. To make your life much easier do this, because after 20 min of trying to remove the old muffler off the inside hangers I did this.. unclamp the muffler, remove the back hanger from the muffler. Pull/push the partially hanging muffler to the back of the car so the inner hangers loop touches the hanger, this will expose a bolt (13 mm), there are two more on the drivers side that hold the hanger to the frame, undue the two side ones. One is easily accessed from the back of the car you can reach in between the bumper and the hanging muffler. The other is accessed from under. Undo those then the single one. The muffler and hanger will drop. "make sure you head is not under it. I just used my body to push against it and take the weight. The passenger side do the same except there are only 2 bolts, the one under the muffler and the one accessed from the back. As a comparison, First muffler took me about 1 hour to remove, passenger side where I just removed the hanger bracket took about 20 min. Tune was simple and instructions were easy to follow. I did have to re-adjust steering feel and it looks like my range to empty will need to re-adjust. I went from 398 km to empty to 511 km) I some how doubt my millage got that much better. Overall a great improvement over the stock exhaust and throttle feel....... P.S the car sounds awesome with out the mufflers and it is really not that loud.

            Love the combo

            Install was fairly simple for exhaust once we figured out the first one. Took under an hour id guess. The car now breathes a lot easier and has a deeper but not obnoxious sound. I have yet to add the tune on yet as I might take it to a dealership to save my warranty a little longer. However I can already see the performance gains! The filters are throw in bonuses! Overall the package is awesome!

            Better Than Expected!

            Enough reviews have been written that I cannot add much more. I didn't really expect as much performance response, through all RPM range, as this little tuning add-on has provided! I agree with one really long review/novel size review (I read twice and made my decision), the exhaust note is PERFECT. Not too loud; I can listen to may SHAKER (w/Crutchfield upgrades) while cruising through town with the windows down, listening to that wonderful burble; or coming home from work, downshift to lower gears when I arrive in the neighborhood to pleasantly announce "I'm home" with the slight pops that make it out!

            Nice Upgrade

            Delivery of the GT500 exhaust, air filter and oil filter arrived 3 days after purchase which was a Friday. Ordered Procal that night and received it the next Tuesday. Wednesday tuned my vehicle my self with the procal, pretty easy but I did have to run jumper cables from wifes car to mine in order to have the necessary voltage. Drove it after tune and yes you can tell the difference, more low end torque and better acceleration. Then installed the GT 500 mufflers in my drive way with help(highly recommended). Im not a mechanic and neither was the help. But it took us about 2hrs total. The driver side muffler is a pain to install, the passenger side was pretty easy. But after a little frustration and a rubber mallet it all went in pretty nice and centered, the driver side pipe sticks out about a cm more than the passenger side. I will fix that tonight. Normal gas milage driving to work was 23MPG, this moring it was 26MPG. So nice gain there. And yes the exhaust sounds awesome. Final note I was going to have ford do all the work. The quoted me $500 for 4hrs of work. Needless to say I went straight to youtube.

            This should be any Mustang enthusiast first mod! Ordering from American Muscle was super easy and the install was pretty straightforward. You need to pay careful attention to the procal installation as this was the trickiest part of the power package but definitely worth the effort! I could of ordered this through other vendors but found AM to have the best price and customer service!

            This was the sound I was looking for! It is not so loud as to be annoying but has a great sound on startup and WOT. Throttle response is really improved and the torque increase is definitely noticeable. I think I got a "steal" on the price and with free shipping made it a double steal. AWESOME street pack!

            should be stock

            My first mustang (2014 GT convertible) and I was very impressed with the handling and performance of the car. One thing that annoyed me was how quiet the car was! I would pull up to cars at a light and i could see them lowering their windows to hear the 5.0! Well they were in for a surprise because the original pipes are Lincoln quite! So being in my 40'S I Didn't want to stand out and scare little children so i did many many hours of research For the perfect axle back. My first choice were the American Thunder from flowmaster. I feel it's the perfect sound for this V8 but when i saw that i can get a performance kit from Ford for the same price i went for the power upgrade! The GT500 axle back are perfect. No drone when cruising and just the right tone when accelerating and at idle. Not the best looking exhaust tips but better than stock ones. The tune....WOW! Still have my warranty and the car feels more responsive! Highly recommend this power pack for those who aren't hardcore sound and power freaks. This really should be stock set up for the GT's. American Muscle was amazing! I live in Canada and received my order within a week!

            I can't speak for the increse in performance yet, but I need to share how happy I am with the way those new GT500 axle back sound. More aggressive while you play with the shifter, same sound levels on the highway. I liked my car, now I love it! I can't wait to see what improvements the tune will add. I had to call Ford Racing' 800 line since the voucher code provided in the box had already been used. Teh agent quickly provided me with a new code, no questions asked. Fast and efficient, the way I like it!

            Noticeable Improvement in Performance and Much Better Sound

            I purchased a 2014 GT Premium Coupe w/6AT, Brembo brake package, and 3.15 rear. As other reviewers have mentioned, I wanted more response and more throaty "sound". The FRPP was recommended to me after I expressed concerns about warranty coverage--nor did I want issues with my dealer. The ProCal tuner delivered crisper shifts in Sport Mode (6A remember) and noticeable low end push once past 1500RPM and improved top end too. Ford Racing Parts personnel were very responsive in sending me the car-specific tune once I received the package (they provided 1 day mailing which was impressive)--and offered great advice--in fact directed me to AM to buy package.) I expect the KandN filter contributes to performance at the margin (the competition oil filter is a nice perk that will be installed at next oil change). The big difference that others notice and I love is the low bass rumble when at idle and then the progressively louder snarl as you go heavy throttle up the gears--no comparison to the stock sound which was too mellow. Turns heads on downshifts but can be almost civil when one needs to avoid undue attention. I can't tell if MPG has improved or not (I normally get 22-23 in commuting) because I'm enjoying the playing with throttle in Sport mode way too much! Dealer agreed to install package and support it under warranty (after a little negotiation) with 3 hour labor estimate at $120 rate. But it was worth it - and dealer service people were pumped when they delivered it to me and said "start her up!". I am very pleased. This is my 3rd Mustang (previous was 1996 Cobra and 1990 GT Coupe) and the best yet in terms of performance, comfort, and style.

            Ford Racing Power Pack

            Great value for the money. The mufflers and tuner come out to $300 each and that excludes the K&N filter & oil filter. Compare that to the Flow Master American Thunder that's high $400's and other tunes that are quite a bit more. The exhaust sounds great at cold start up and WOT, but are as quiet as stock and cruise speed and if idling for a while. The PROCAL tune is an amazing value! It changed my Mustang for the better. I noticed more aggressive throttle response, the car pulls harder and greater responsiveness. Paid $85 for dealer to install which is worth it to not void warranty. Since I have a Rouch CAI, I ended up selling the K&N on eBay.

            Setting a new baseline

            As stated by some other reviews, this should be how a stock mustang sounds and handles/reacts. That being said it would be great if the mufflers were a little bit louder at stable speed, because they're *really* factory quiet when cruising (and quite close when warm idling) which is kind of a let down. On the other hand, they are quite loud on acceleration, maybe a little too much because even quite smooth acceleration make it seems like you try to break some record. But hey, no regrets at all here, just nitpicking. It's worth noting that cold idling is awesome... like... really awesome. Also the included tune is nice for city driving and highway overtaking without downshifting. A real plus for daily drivers.

            I own a '14 GT Convertible w/6MT and 3.31's. I wanted something with a little more "sound" and "oomph." This package hit those spots well. The nice deeper rumble when I start the car is great, and it's "quiet" when I need it to be (neighborhood, or when I have the top down and the old lady in the car) and roars nicely when I want to play. The tune made the car come a bit more "alive", and I also think I picked up a mile or 2 on the mpg; however, if you really want a pin in your seat experience through all gears, think 3.73's are the way to go (....maybe next year?). I ordered from AM (love all the videos and the reviewers posts) and had it shipped direct to my dealer. I then stopped by the dealer once in, took the procal sheet home and ordered it, and once the procal arrived at my house I made an appointment to have my dealer install it all. Labor was $250, and it took him ~2.5 hours (includes oil change, axle backs, change air filter, tune, and re-box old stock mufflers). Anyone need a set of stock mufflers with ~2500 miles on them?

            This is the best addition to 2013 & 2014 Mustang GT owners that don't plan to track their car all the time. The throttle response is improved and the torque in the lower RPM range is really noticeable. My gas mileage has improved as long as I keep my door out of it which is hard they way the GT500 mufflers sound. American Muscle is fantastic the product arrived within 2 days and was really easy to install. In fact if anyone near Atlantic city that orders this kit and needs help just let me know.

            Gives the butt dyno a bit more of a jolt but doesn't seem that much faster. Much better throttle response and low end. IMO, this should be a base tune that ford should put on the car. I love the deeper/throatier sound that the axle backs have. Not too loud. Has a great growl.

            Product performed as promised.

            Ford did an execellent job in putting this package together. The exhaust note is identical to a late model Shelby whether your are cruising or hard on the throttle. The programming also delivered the goods as follows; (1) Bottom-end was noticeably improved and made driving car in town much more enjoyable. Starting in 2nd is now as easy as it was starting in 1st before the update. (2) Eliminated the annoying 1st to 4th economy shift feature. (3) In addition to an overall power improvement, it has improved fuel mileage as well. (4) K&N filter and Ford Racing oil filter is icing on the cake.

            Just what the doctor ordered!

            The FRPP basically "fixed" any disappointments I had with my '14 GT. First off, the GT500 axle backs sound mean- but not obnoxious. Turning the key on a cold start always brings a smile, there is a nice grumble during acceleration, but things stay "civilized" during highway cruising. IMO, these mufflers should have been included in the Track Package from the factory. The only drawback was damage to one of the exhaust tips. The packaging isn't sufficient to protect the tips, and one of mine had a nasty ding on the top of the lip- which took about an hour for me to straighten. I should note the packaging seems to be done by Ford Racing- not AM. The tune absolutely fixes the car (again, this should be the factory tune for the Track Package, IMO). I feel a lot more torque down low, and- most importantly- the accelerator acts the way it should (i.e., immediately and consistently). The result is the shifts through 1st, 2nd, and 3rd become much easier, smoother, and more satisfying- AND there is no more issue with stalling when I back up my driveway. Finally, it really makes 6th gear more practical (no longer have to shift to 5th for passing on the highway). Registering the Procal is easy, and it arrives the next day. I installed the mufflers myself (bending the forward mounting rods up slightly at the ends makes installation much easier- but doesn't affect final mounting location). To keep the warranty, I had my dealer install the tune (they charged $232- be sure to be clear on how much the install fee will be... it takes about 20-30 minutes, but my now former dealer charged me 2 hours labor). All in all, the FRPP produced the sound I was looking for and the street performance a 420hp car should have.
