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...
