Help is greatly appreciated. I am working on a Procharged 2006 Pontiac GTO with an LS2 that I am unable to tune. The car was running fine until the owner rebuilt the engine and installed a cam. Now the only way it will idle is to almost max out the VE table values at an idle. The wideband shows it lean and it appears to want more fuel. It won?t rev and the wideband will go lean when you do. VE is maxed out in that region. The engine has good vacuum and I have sprayed it down looking for a vacuum leak. I have checked the cam timing and it is fine. The rail pressure is steady at 58 psi when running. I have tried 2 sets of injectors. The voltage to the injectors is good. I have checked the grounds and they are connected (back and front of engine). All of the sensor ranges seem normal. TPS, MAP, IAT, ECT, etc. There are no codes set. I am out of ideas at this point. This was a running tune prior to this, so I am suspecting something electrical/mechanical? Any suggestions, or ideas on what could cause this would be greatly appreciated.
