ok i took off my manual boost control because the bearing was alittle big and got stuck. so i put the stock boost control back. but it doesnt work. it passes 22psi and it fuel cuts.
why is it like that? and whats that hose for that comes down from it that goes in the intake track?
sometimes it controls it but only in the first two gears.. so i dont get it
well thanks

Enjoy it! Just kidding, connect the line coming from the compressor to the line going to the wastegate to keep boost down and prevent blowing up the motor, until you figue out wht's wrong.

my car does the same thing. so i also took out the mbc and used the stocker, and it still goes past 8.9. i think that is a lot of my intake popping or detonation. whenever it passes 12psi, it pops. i can feel the pop through the gas pedal, which means that the popping is a detonation in my intake which put a large force on my throttle body butterfly. i have a lot of reducers and enlargers in a vaccum line where my morgie fuel cut defender was, could this mess things up?

Yup the differening ID reducers/enlargers could definitely throw things off. Keep all the lines at or near stock ID. If there's too much flow for the boost solenoid to handle you can have erratic boost control. I can get you a bunch of 4mm silicone vacuum line for next time you stop by if you want to replace all your old lines with ones of the same size. Your lines may be cracked or starting to crack as well.

That popping is detonation inside your combustion chamber which puts a large force downwards on the piston which is still traveling up- VERY badTurboLegacy wrote: that the popping is a detonation in my intake which put a large force on my throttle body butterfly.
