I've been tuning an 05 GTO, in which we just installed a VRX5. The car has been going into safe mode intermittently, usually a mile or two after going WOT. I don't have scan of it when it does this, but here is the tune file and the DTCs I pulled:
[ECM] P0068 - MAP/MAF - Throttle Position Correlation (History) (Immature)
[ECM] P0101 - Mass Air Flow (MAF) Sensor Performance (Old) (Immature)
[ECM] P0106 - Manifold Absolute Pressure (MAP) System Performance (SES) (Old) (History) (Immature)
[ECM] P0300 - Engine Misfire Detected (SES) (Old) (History) (Immature)
[ECM] P0068 - MAP/MAF - Throttle Position Correlation
[ECM] P0106 - Manifold Absolute Pressure (MAP) System Performance
[ECM] P0300 - Engine Misfire Detected
Is the MAF tuning causing this? Did I miss something when turning the MAF back on after VE tuning?
