MAF Scaling - Calibration

Once you have a good tune, it is time to write it back to the PCM. First in the VCM Editor go back to Engine \ Airflow \ Dynamic tab \ Dynamic Airflow section \ and set the High RPM Disable back to 4000 rpm this will re enable Speed Density to assist the MAF sensor in metering air

then save the file with a new name something like 02 - MAF Calibration - Tuned.hpt
