I ran a 13.7 @ 100 with just a CAI, Flowmaster Weld-Ins, 4:10 gears, and a mail order tune from American Muscle in my 03 GT. In stock form down to the ***** looking air filter I ran a 14.1 @ 98...DA was 1727 when I ran the 13.7 at Fayetteville, NC.

 

^ feel like you wasted your money? or is 14.1 to 13.7 feeling gigantic

 

Im not sure how he ran 14.1 in a stock auto car but my brother 2000 auto went like 14.4-14.5 bone stock, with 4.10s it was around 14.0ish, tuned and a few bolt ons it was doing 13.7~, with a 3800 converter it dropped to 13.2s

Theres a huge difference between a 14.5 and a 13.2, thats for sure.

.4 at the track is actually a pretty significant improvement believe it or not

 

I live done South in Florida. Whether prob High 70s. I have not ran often so alot of the time is on me rather then the car. After I put a 100 shot on it and ran a 12.7 and that was my last time at the track prob in March.

 

I felt it was a waste of money. Should have kept it stock...As of today the car has 19,857 miles on it...

 

like every one else has said gear,stall,tune will be in the 13's easy my car went 12.76 but its a full bolt on 5spd but ive seen bolt on auto's run 13.0-13.2
