Hello,
I would check for a partially clogged exhaust. Sounds like the engine is not breathing good enough to me. Could be a partially clogged cat or muffler.
I would loosen up the head pipe a little so you have a little gap there and run it and see if spools up and runs up to redline that way. If so your problem is somewhere in the exhaust.
If not I would check the air cleaner and maybe try another MAF. Good Luck, Bernie at George Riggin Specialty Automotive
