I have a 03 Gt auto do you think with a CAI, offroad X, catback and programer i could run a 13.5 to 14.0?

 

hmm i would say u might be able to be high 13s but probably still low 14s

 

I took it out to the track stock and my best was 14.6 with a avg of 14.8

 

i'm gonna say 13's are still off limits for you. do gears, and get some DR's then you might see a 13.7-13.9

 

A stock auto pi-2v should be running 14.2-14.4 depending on track prep and altitude. You running a 14.6 and averaging a 14.8 is telling me the track sucks, your altitude is killing you, or you just dont know how to drive. I think with your mods a tune you should atleast be running 14.0-14.1, but if your fastest is 14.6 and you're averaging a 14.8, the best I can see out of those mods is a 14.3-14.4.

 

It is possible but I say 14.2

 

What a big difference between man. and auto. Procharger did a run w/ an 03 gt manual to show a before and after with a 8 psi P1sc kit. It had slicks but the only mod was a cat back exhaust. It ran a 13.67 in the 1/4. Are auto's slower because of the trans.?

 

put 4:10's in you will run a 13.50 or so. I run 13.50's all day with just x pipe,cai, and gears on nitto street tires. you can buy a tuner and tweak the adjustments on your auto. I also did the j mod valve body conversion and it really helped the performance on my auto. these auto trannys are pretty tough and there is a lot you can do to make them perform vary well.
