Then i took it to the local ford dealership with and svt specialist on staff and had it tuned like a lightning. following this was magnaflow exhaust and high flow cats with jba shorties. To top it all of there was a little trans work and 4.10 gears in the rear. I also threw some lowering shackles on the back to drop the *** two inches so it sits level. I think with a new tune and a head swap i could get down in the high 11's or low 12's. All of this was done for around 8,000$.
