Garrett GT2860RS turbo kit, 80's, 1:1 mix, 1 step plugs.
I have been tuning this LS Cobalt Turbo and we are having some issues.
After driving he will put the car into park and it will die. TPS drops to about 4% bogs and dies. I have the scaler set to his upgraded TB, just not too sure what it is.
Also, in second ONLY, at WOT anything above 5k(ish) RPM it misfires bad! He checked the gap and everything was fine. He lessened gap and it didnt help.
This misfire issue has been happening with his trifecta tune and also with the HPT tune so maybe its mechanical? It only happens in second and we didnt have enough time in to log it this time but before we went full throttle to 6500 in third and it was fine.
