I just put a z32(n62) mafs with a j30 harness, onto my car and now it's running really bad... It sounds like it has a wicked cam, and black smoke is pooring out of the exhaust. I took it up the road and gave it some gas and it fell flat on it's face. Almost like detonation. I was wondering if I had to have my car tuned to run this mafs?
