All 2015 Supercharged Roush cars need it for an aftermarket tune. Just like all Roush cars need to be flashed a stock tune before an aftermarket.
Allows all tuners to pick up IAT after the blower.
A little late on this
I had 285/35/19 RE11 square setup on 19x9.5s. Only tire I had to compare these to is the stock Pzeros. Grip was great far better than the Pzeros. I only drove maybe a total of 500miles on RE11s. Definitely had more confidence when cornering and they are way more predictable...
Built a GT350 with tech pack, black roof and stripes and it was still in the 57 range. Im not sure why they are saying Supercharged. Doesnt tech pack come with Voice activated nav and heated/cooled front seats?
Yes and No, Just sold my 15 Base PP w/ Recaros. It was a great car but im going to wait until the end of the year and see if there is a refresh for the 17 model year.
