I have a P0101 code on my friends 07 LBZ after installing a 4.5" intake. How do i go about tuning the MAF? I know where the MAF Airflow vs. Voltage table is....what should i be logging to determine how to recalibrate the table? i know its nothing like gas motors and that too much fuel could melt pistons...that's why i haven't messed with it yet. i've not been able to find anything too informative yet on this subject.
