Car Seems Slower After Mbc Install

[TheRealist]

I Installed everything corectly becuase my friend did it and his car realy pulls hard and he did it the same way he did his car and we both have same turbos, my car just seems slow as hell and i dont have any boost leaks either, we have it turned off the MBC But my gauge is reading 13 PSI UNTILL 4 RPMS THEN READ 10 OR 11. BUT IT JUST FEELS SLOW EVEN WHEN I PUNCH IT ITS NOT PULLING VERY HARD.

You should fix the loud whining problem from the last thread you just started. That most likly has something to do with it.

Boost leak test?
