alright, I've been reading around and deleting the rear o2 on these cars is common enough. Previous owner had it tuned perfectly, I thought I could do it better, couldn't, now I need some help. Seems like most people say to drive up to intense? I looked on their site and they said its $100 extra if your car leaks anything on their dyno? My car definitely will. I don't need a nice expensive dyno tune, I just want it to run right. Any suggestions?
