^^+1. Yeah i was kinda thinking the same thing. There is no reason to use that mbc. I would get rid of it and go get a protune. Even if you get an accessport there are no off the shelf maps that will support a fmic. You can get one if you want but in any case you still need a tune. Yeah the guy that sold you that car didn't do it right man. That turbo is not a big turbo so 400 hp is really not even a realistic number. And just an fyi. My car with the factory turbo just a turboback and accessport is hitting about 16 psi on 91 Oct. Im sure whatever he has done is wrong. Good luck man.
