Oh damn, just saw this, I’ll reply anyways lol. With my intake, flex-fuel kit and a tune I am pushing 470 to the WHEEL. GP Tuning(Matt) is an incredible GM tuning god. Very respectable tuner in the GM world 10/10 would go back and recommend others to email him for more information. He is a busy guy so good luck.

QUICK QUESTION, WITH THE TUNE AND INTAKE, HOW MUCH POWER ARE YOU GETTING OUT THE CAR? ALSO... HOW REPUTABLE IS GP?
