[QUOTE="jpplaw, post: 14373523, member: 152740"] Yeah, most likely the new tune is way off on the MAF transfer. Can you keep it running long enough to datalog RPM, MAF counts/voltage, airflow and AFR? Unplugging the MAF makes the PCM run off the LWFM table instead of your MAF tables, so it doesn't really mean anything - the problem could still be the sensor itself or the tune. A datalog will tell you if the MAF is 1. putting out anything, and if so, 2. if it is a decent curve, and 3. if it is the right curve. [/QUOTE]
