Re: 5.3L Truck MAF? We've got one of the truck MAF's on Jason's 422 TA. It corrected a lean condition the custom tuning didn't account for. Its the same replacement part number as the LS6 MAF also. Supposed to be 20% rich on a stock LS1 from what I've been told. The wiring connector is like $15 and you have to get the wiring connector wired just right, there are three MAF wires. Positive feed (marked +), Ground (marked -) and Frequency (marked F). These markings will be on both MAF's and you need to match them up ... plus to plus, minus to minus and frequency to frequency.
