Geez you kids are retarded.

The MAF is a HOT WIRE MAF - OK dimwits, now when you start pumping huge amounts of hot air across it, far and above it's original design of ambient air - it basically doesn't register the airflow correctly. So stop being frickin ignorant and listen!

Also no turbo on this planet is 100% totally oil sealed so you WILL coat the MAf wires and ruin it's efficiency further. I don't care how good you think you or you turbo are.
Ah sh!t, do what you want - I wanna be the first guy to point and laugh when this engine goes boom as well.
