The truck computer will not work with a 98 f-body harness. The 98 computer and the 99+ computer have different pin outs. What maf are you using? And did the MAF problems start when you tried to plug in the truck computer?
Your posts are tough to read, but from what I can interpret you've got a '98 harness and you're trying to use a '99 PCM.
That won't work, the pinouts are different as previously posted. Probably fried the '99 PCM you tried.
I suspect the MAF error is just a calculated flow defect, because you're only moving 5.3L worth of air and the table is calibrated for a 5.7L engine.
Take it to a tuner with the '98 PCM in and have him work the calibrations to match your engine.
