Re: pcm swap for mileage?

Swapping to a newer PCM wont do anything but give you troubles........i know the 02s are all different because when i swapped trannys i tried an 01 PCM and the truck hated life...........Something might be wrong with your PCM, If i were you Id send it to Jody have him look it over and maybe re flash it.

Remeber that it is winter time, so you burn more fuel warming up and cooling down.......Try a fuel additive like Stanadyne or something....See if it helps...

Re: pcm swap for mileage?

Yes, you can put a chip in as the chip over-rides the PCM programming.
