This was my experience and it's why I've been such an advocate for this mod on the GDi V6, it's personally the best mod I've done to the car, even over the canned tune and the suspension stuff.Car feels more responsive mid range and revs a crap ton quicker. I don't want to sound like a sissy, but I'm a little afraid of the car now. I did my normal round trip around the lake and mountains and the car is different. I'm going to have to relearn the power band. The TC light kept flashing while doing things I have done at the same speed/conditions many times and it was getting squirrely.
