. Sounds like a good upgrade in performance. Do you have other mods (CAI, exhaust cat back etc) or stock?This will probably be longer than it should be, but several important points need to be addressed.
I had my local Ford dealer install the Performance Tune (FPT), following the suggestions from Ford Performance (SVT) with respect to the installation, warranty, etc. However, the exact procedure was not followed, hence the 3 day delay of getting the tune installed, including the local dealers ill-advised paperwork ritual. There are abbreviated instructions in the box, but youād best down load the full instruction from SVT. And just like the bold text comments suggest, follow the instructions to the letter!! Make sure nothing is plugged into any of the USB ports including the one behind the center mirror.
As a side note, one of the issues involved the short-staff situation at SVT, due in part to the upcoming holidays. Kudos are warranted for both Tony and Tom at SVT, as these are the guys handling all of the techs and owners complaints when they cannot (or didnāt) read the instructions. Their holiday off time is going to be well earned!
There are a couple of things anyone contemplating installing the FPT. First is the tires. My Mustang is a simple Eco-Boost Premium, with 235-50ZR18 Blade Spoiler all-weather Continental tires. Traction-wise, they stink! Even at 60 mph, full boost (ā24.8 psi peak, dash gauge reading) will cause them to lose traction with predictable results. Those with the PP upgrade shouldnāt have any issues.
The FPT is supposedly an update to 350 HP and 400 FPT, but I wonder about that rating. On the dyno, the stock setup produced 311 HP in Drag mode, which would indicate a power rating close to 325 HP. Allowing for a the seat-of-the-pants guesstimate, it feels more like 375 HP. I only made a couple of 0 to 60 runs because of the loose tire situation. The second one 4.3 with a ton of wheel slip from about 10 mph clear to the 60 mph point. Frankly, it is almost scary and Iāll need time to get accustomed to the lack of tire slick. I do have a plan in place to update to wider and stickier tires. But since Iāve never liked Continental tires, they wonāt be any of theirs.
Just once for fun, I switched to Drag mode to see how the line lock worked. Previous to the tune, you could spin the tires easily, but with the tune the tires turned to smoke and screech owls! Good way to please the local gendarmes to be sure! Maybe I should buy some of those colored smoke tires?
The bottom line is, the tune is more than worth the monies spent. Speaking of which...
The tune lists for $850 and the street price depends on where you buy it. The labor cost varies too, but with one minor addition which didn't have anything to do with the tune, the total was $485. The original estimate with $195 which they stuck to, but $48 for shop supplies and tax were added on. Whatever, I'm pleased enough that the cost was not an issue.
