i just installed the Forge MBC (replaced the n75 valve), put the right connections, but dont know what to do with the n75 sensor wire since it is not plugged in anymore.. now i took it for a test drive, and now my car does not idle smooth.. when i drive it and boost is supposed to pick up, it vibrates and jitters like it cant produce any boost, making a weird jiterry sound.. does anyone know what could be the problem??


any help is much obliged!!!

 

keep the N75 plugged in just zip tie it to something that its not going to come off of and it should run fine.

 

it still runs weird and vibrates/jitters under boost.. almost sounds like im running off of 3 cylinders, but its only acted like this when i replaced the n75 valve with the MBC..

hmmm.......

=\

 

thats why most people just leave the n75 unless you are doing other modifications and need boost control.
