Haven't been to a track but I've got some times using my G-Timer.
Mine is an automatic.
Stock my best was a 15.2
90.6, 2.32 60', 6.9 0 to 60
After tuning w/ XCalibrator best was 14.9 @ 91.6, 2.2 60', 6.42 0 to 60
After adding CAI best is 14.78 @ (94 I think, forgot to write it down), 2.15 60', 6.35 0 to 60
No improvement noticed after adding axle back exhaust (except it sounds better).
The stock 15.2 run was hard to duplicate (had mostly 15.4 & 15.5 runs).
The 14.9 w/XCalibrator was backed up with some 15.0 & 15.05 runs.
The 14.78 is backed up with a lot of 14.8 & 14.85 runs. As long as I don't spin the tires too much I can usually get around a 14.8.
JBA headers should be here soon.
I think a set of 4.10 gears should get below 14.5 easy. (I'm still thinking on that change though).
I know the G-Timer may not be completely accurate but it shows how much the changes have helped my car.
