Ok nothing is solved so let's start fresh.
*new info* Car runs like a champ with MAF unplugged, issues are only with MAF plugged in. MAF and ECM have been replaced, original ECM is back in the car as it saves me $$$
It HAS to be something the MAF is affecting but I can not for the life of me figure out what it is...
Subaru had the car for 3 weeks and the only idea the tech line gave them that they didn't try was oil control valves. *new info*
Ok long story short I flashed Cobb stage 1 and this arose, tried many things and the issue remains.
Car runs perfectly up to 4500 rpm then it just hits a wall, feels like fuel cut or hitting the rev limiter.

I have tried flashing stock map, flashing stage 1 again, completely removed the AP from my ecu.
New fuel pump
New fuel filter
New MAP sensor
New front O2
Disconnected battery for 12+ hours.
No vacuum leaks of any kind.
Not one CEL.
The problem persists unchanged.
Any ideas from folks wiser than myself?
