D'oh.... I didn't remember that this was a swap. Please put your truck's details in your signature so people reading know what you're dealing with.
I would definitely check the AFM's wiring, especially if the TPS wiring was the fault in your last thread. Is the fuel pump resistor and relay in place? From what I recall, on the 7M's setup bypassing the fuel pressure up VSV would cause issues with warm starts and warm, low load performance so you may want to try running the vacuum line to bypass it for diagnostic purposes.
