    I'm overlooking something if some one could look this over and tell me what a dummy I am. Most of my problems are coming to a stop at operating temp and going into gear at operating temp (more so going into Reverse for some reason) ive been searching forums and treads. I'm just stumped any help would be appreciated

    First thing is ---Are you trying to run in SD ? If so, Go to engine diagnostics--DTC's and set P0101,102,103 to MIL on First Error. Retune. Looks like you have almost double the amount of Base Running airflow that you will need. Airflow--Dynamic--High rpm disable--8,000. Power Enrichment--Enable min MAP, 85kpa. Delay--RPM, 0. Delay--delay, 0. Boost Enrichment--EQratio, 1.27 across. I would make boost enable 105kpa, but that's my preference.
