The only guy I ever heard of that made good money tuning was some guy from the west side. I met him one day at titan motorsports when I met up with titanium and some friends and he was tuning some jdm rhd FD rx7 that had a dbb turbo and aem. Seemed like a cool guy, suposidly big in the tuning world. Maybe titanium will step in and help me out on this one.
