I checked the harness at the valve cover and everything looked good.
I decided to go after the low boost code and found the MAP sensor was 2 pounds lower than BARO so I put a new sensor in and it still read 2 pounds low. After testing the wiring I put in my spare PCM and the sensor started reading correctly and the surge was gone. I sent the PCM in to Reman Auto Electronics and they rebuilt it and it works great.
The IDM came in Friday and I installed it and all tests pass. I guess from now on if I need a 7.3 IDM I'll go with that company even though I don't like going aftermarket, especially with electronics.
