I am having the hardest time figuring this out. This is an 07 Z with built motor and supercharger, decent size cam. I have the tune down. It starts and idles perfect. I have VE disabled.
When I get on the gas hard, it starts to rip and then about 1 second later goes into reduced power. I check the codes and just one code: P0606.
Throttle body is STOCK.
Electronic throttle section in the tune is ALL STOCK. I have never touched any of this stuff. I also compared it to a stock file and it is the same.
The computer was recently replaced by the owner, but everything else is fine. There are no other issues. Could this be a wiring thing? It is only when I nail the throttle.
Please help! In over 200 cars Ive tuned Ive never seen this.
