He advised he would basically run the same tests to see what's going on, but it's really just a guessing game at this point.
I'm super frustrated, but there really isn't much I can do right now. I'll continue to post updates whenver something is worth mentioning.

Yeah, that's typical mechanic behavior. I'm surprised he didn't say to replace the PCM too. That's what they all say when they can't figure it out. I understand your frustration since it's probably a simple free fix most likely. Did they plug in a scan tool and read live data. A good scanner should tell you if the truck is in limp mode or not. And monitor TPS input and output signal to PCM. Have you observed the throttle body plate while someone is in the truck depressing the pedal. There is something you can do about it now though if you desire. All you need is a multimeter. I would pull the codes manually. There may be other trouble codes the mechanic ignored and could be good clues to the source of the problem. Then use the multimeter to find the issue. All this can be done at home for free. That's not correct PCM relearn procedure I don't think.
