Need some advise, I have a 2013 370z (sport) wouldn't take the UpRev tune program, sent the dump to UpRev but they couldn't find anything wrong with the program, I have the following Mods on it Stillen G3 CAI / Berk Test Pipes / Stillen CBE.
Thinking about taking the Test Pipes out and replacing it with either HFC or LTH
