New ECU is in. Starts and runs like previous. Will not rev above 3000-3500 rpm, no power. When inline spout is pulled, runs like a lack of power, but will rev beyond 3000
Unplugging MAF sensor at connector does not change idle or running

Called Ford dealer to cross reference part numbers. F07F-12A650-DA cross references to FOTZ-12A650-DA
Ran two different MAF sensors - An aftermarket Spectra Premium MA223, and a Ford F0VF-12B579-A2C. No difference
I'm starting to wonder if I have the MAF wired wrong. The only changes I made to my harness were to add the MAF sensor inputs and outputs to pins 14 and 15, and the MAP sensor 12V hot and ground. No other changes.
Checked MAF leads with meter. It is getting voltage and outputting signal.
Left my MAP plugged in. Disconnected the hose from the block and capped the block side.
Really stuck on this one ?
