Ok, when I do a WOT run in like 2nd or 3rd gear(all the way to redline) right after the car seems to fall flat on it's face.....like you tap the gas and it's very late in it's response, which makes it a PITA to shift gears smoothly, and to take off. Im trying to figure out what is going on there, because I turn the car off and then right back on and it's fine. Is it something in the PCM, or the tune possibly(gm stage 2)?? Any feedback would be great.....
