Last couple months I purchased a 13' RR Boss 302, very clean car 4k miles one owner, no accidents no claims, never tracked - the original owner had never even done a burnout in the car. I was sold the car as track key enabled, when I picked up the car turns out it wasn't installed. Long story short, the dealer went good for it and ordered the track key install/kit. Just finished the flash today and what a difference! The throttle is much crisper, haven't noticed a huge difference in engine braking yet, but I do have to say with the baffles out the lopey idle sounds great. I love the slight shake to the car reminiscent of the old muscle cars. I have an auto cross race this weekend so I can't wait to see how it performs!
Anyways thought I'd pass it on, that you can still get the keys, they now come with a K&N Filter and Ford Pro call tool - pretty slick process. Hats off to ford racing for how they do the whole program. Now I've got a code reader, not to mention if I change tire heights I can re program the speedo myself. Pretty cool!
