so i got the correct size hoses today from ecs and hooked em up. i dont want to use my n75 at all other than it being plugged in electronically. i have a forge mbc with three prongs. i hooked up one line from turbo into the left prong then the prong on the right to the wastegate and the prong on the bottom into the intake. but i still only get like 8 or 9 psi??? what am i doing wrong???? is it the pos forge mbc?

 

Im sure you have seen this but maybe it shouldnt be hooked to the line on the turbo but a different on from the intake??

the way it is shown is the way i have it hooked up.

 

hmm that sucks, and you turned the thing all the way up

 

I have that same one in mine. No problems. I left my N75 hooked up with a vacuum line going from the turbo port to the wastegate port.

 

you may have it in backwards, i know that the way mine works is that it bleeds of pressure to the wastegate. so i get more boost when i turn it down cus it closes the mbc there for not letting the boost get to the wastegate, and if i turn it up i bleed of pressure to the wastegate and it will open, u could have a bad wastegate also

 

i dunno ...at this point im thinkn of putting a match in my gas tank and solving the whole problem.

 

Thats why i never played with mbc on my 1.8t, more of a trouble then help unless your setup really needs one.

 

black991.8q where do u live?

 

chicago subarbs.... i tried hooking it up different but nothing happend. i think im going to sell my forge mbc ang get a 2 pronged style. maybe a hallman pro or sumthing.
