Your telling me! I build and tune a lot of high performance cars at the shop with larger injectors and turbos the whole 9 and have never had any issues like this, one where the calibration seems to have little effect on what’s happening. I always tell my customers the same thing!

What are you using to Tune with, HPTUNERS or Diablo?
What supporting mods have you done, like a T stat the small stuff?
