Car is running....but problems....

Hey guys, got the car running today. I think i may know the culprit for my problem(MAF). Anyway, the car idles fine, but when i rev it, it hesitates and and doesnt rev. The MAF is a universal pro-m blow thru that i had on it with the turbo setup, with 42's, (yea yea yea i know i know) but i was hoping to tune around issues with my PMS. Timing is set at 13* base. Not sure what else could be the problem.....any ideas?


Thanks
Nate

Lol ha ha. its just the explorer motor now. long tubes and prochamber are the exhaust now...everything else is the same. same maf and 42lb injectors. It didn't do this back with the turbo...and the turbo made no boost. it almost feels like when my maf came loose a long time ago...but it idles perfectly. can i tune with a wideband and pms around a maf that doesn't match the injectors?

Put in my stock maf and its good to go! but now the oil pressure will come.....and then leave....at least on the stock and autometer gauge. any ideas? I'm hopin its just electrical....gonna pick up an mechanical pump tomorrow......
