He didn't do anything besides turning the traction control off. It was blinking and going crazy the whole time, but it didn't stop us from getting a good dyno read out. He said on some Mercedes and a lot of G35's (my prior car) that the traction control prevents them from even doing a dyno. We had one run that didn't work out so well, but the other two that you see were fine. Does anyone know anything more about the pinging issue with the Upsolute chip? Because he advised me that i steer away from any chip that causes even mild pinging as it could be very harmful... on a good note he said that he's seen really good chips that produce up to 30 hp on N/A engines.
