My car performs great ... I mean anytime I measure a rolling start I always see an improvment over my stock times. IE: 40-100, 40-60, and most importantly my 5-60. However, anytime I measure my 0-60 no matter how I launch the car I always either hit a 5 flat or 5.25. On the other hand my 5-60 runs are always around 5.1 seconds. Shouldnt there be a big difference between my rolling start and a 0-60? Road and track got a 4.9 on a stock mustang for 0-60 (perhaps this wasnt the norm). I have an extra 25rwhp. My question to you guys is do the mods really help a lot more up top then they do down low. I mean 0-100 which doesnt factor in the launching so much is somewhere around 11.7-11.9 which is phenomenal over stock. I suppose it could possibly be the 32k miles I have on my pirellis or I just dont know how to launch my car anymore. I just want to see 4's thats all.
