anyone ever use pcm for less?
I came acorss there site and then looked up reviews about them. some people loved it. others din't. I have a 1998 z28 with a lid,exhaust,k&n filter and an electric cut out. I wanted to know If they did good work and what my gains might be with my little mods? They claim 10hp if the car is stock. I was kinda hoping more like 15hp.
