Its a diesel and does not run at a set AFR. So even though you are trying to fool the cars computer by "enhancing" the MAF. The computer should be smart enough to say what the hell that cant be right then ignore the MAF and run in speed density (SD) mode or run off a back up table that will guess the amount of air incoming using other sensors and info like gear, RPM, Air temp, and MAP (air pressure).

My 98 Bonneville could even do that being gas powered. How do I know... I ran without the MAF to tune SD for a fall back and to help smooth transients.
