E67, speed density it never did this but switched to MAF mode because hit a wall where it seemed not to be able to calc properly past a certain power level.
Make clean pull everything looks perfect but after youll hear a pitch change and TPS at idle seems to lock out at a high number - causing idle timing to go way negative and make the car run like dookey. Thing is reflash it and it goes back to idling and acting normal??? I never really mess with MAF mode on higher power boosted cars never ran into this before. Run10 is a pull in SD where you can see idle tps returns to much lower value and idle control timing acts normal after pull
