new car, new problem
Hi everyone, I just bought a 98 z28 a4 about a month ago, and after i bought it was told that someone had used a hypertech on it. It seems that they upped the tranny line pressure a lot. Well I am about to install a converter and shift kit and I want the pcm set back to stock so i dont blow my tranny. Is there any way I can do this without paying the dealership or buying a hypertech?
