The MAF flow ~matches a stock LT4 dyno log I found. It made about 170 kPa on the MAP @ 4600 lb/min on MAF. You are hitting 108 kPa @ 4500 lb/min and he rev'd a little higher.

Maybe a bad MAP sensor or logged channels? Not much to go on with parameters you logged, try the set I uploaded. There some stuff in there for M6 car (clutch related) and WB02, ignore those for your logging purposes.
Thanks for the reply! I loaded your channel set and did a few runs. See attached. The second set I did w/o the A/C running, not that it made a difference. What do you think?
