My tune kept getting better and better every time I drive it.

 

I punched it from a stop comming home from work a few nights ago while messing w/ a Vette and It still surprized me. And I've got a couple of thousand miles on it since he last flashed my PCM and the only thing I had him change then was to raise the shift points 100rpm and raise my downshift mph up on the 3-2. I say like others "give it time." JMHO...Zed
