MBC installed.. Some WEIRD problems

JC1990 is absolutely correct. This car needs a tune for more fuel!
...and it will need a cat

I dont know about lean misfires.. becasue it was doing it at idle, and below when the turbo spooled.
but it went away today... i didnt do anyhting to to.. just came and went like cold.. im guessing i had bad gas, as soon as i filled back up it was fine a few min later

It sounds like he might have burnt valves seeing that he is now stating that it is now back firing out of the intake valves. He needs to do a compression test on the engine.

I can confirm that the ECU can handle the added boost. I have a mbc set at 15-16psi for years now and I actually had to PULL fueling bc the car was running rich. Sooo dont tell people it cant be done, or it will blow the car up, its just wrong information. Ive got a b6 tho, so that may make a difference.
To the OP, you have some serious issues going in with your car. Stop boosting, remove the mbc, and get a compression test done before you do some permanent, expensive harm to your engine.

try gapping your spark plugs? what kinda gas are you running? try cleaning your MAF for a better reading. but seriously, take your MBC out to see if your car is even drivable anymore.
