2003 chevy trailblazer_ls
Just got my PCMforless back today. Went home to put it in at lunch. On the way back to work, I did some "testing". Wow, runs to 6 grand in a hurry and shifts nice too. I still cannot cut the wheels loose. Not that that is a big deal but, maybe I expected to much. I have a gutted air box with a k&n filter. Does anyone have a I6 that can break'em loose?
