Is there a relearn process or something after the MPFI upgrade? Truck runs good with misfire and hard start when hot issues fixed but fuel trims still whacked.

So far your right. A few misfires but nothing like before. I'll still seek to address that. This was the ride to get gas this morning:No relearn. Those fuel trims look good.
So no misfires? And no "crank-no-start when hot"? I think that's what I understood you said?
They'll likely improve slightly after you drive a bit more...
