Hi. I own a g6 gxp street edition, with the v6 3.6 VVT, and i was wondering where and how can i get it tuned?
I also would like to get some of your opinions on the k & N filters, and crab intake. Please incude what it does to your car ex. how much horsepower etc. (Since i wanna buy these, but i would like to get some feedback before i go spend money on them)
