Sorry for taking so long to respond. Well it would never go into REP when it was off with the key on. I could hold the pedal wide opened all day, and it would work fine. Well when I started turning up the boost, it would go into REP. I always got P2101 for a restricted throttle blade. If I left the engine off with the key on, and forced the blade closed with my hand, I would get P2101. I decided to start logging the pedal position, and the throttle position. Well the pedal was always working properly, but the throttle blade was slightly closing at higher RPM's, and forcing it into REP. I made a divider that let air split easier in front of the throttle body blade. Well it helped a little. I heard that the LS2 throttle bodies open in the opposite direction, so I bought one. When I hooked it up, it worked great. I will be turning up the boost soon, and will see if the LS2 throttle body continues to work properly. I will keep everyone updated.
