We do have a couple of code readers. Might have a scan tool too now that I think of it. That would be great to go for a drive and see what's happening.
Just for kicks I had someone put the truck in gear and hold the brakes, with the timing light hooked up just to watch the mark (wire still plugged in), it wants to bring the mark towards 0 when accelerated under a load, VS. advance the timing.
Edit: Forgot to add... Checked the TPS and MAP sensors with a meter, voltage looks good. Also checked/tried swapping the square ESC block on top of the manifold, seems okay/no difference.
