Thread: Boost by pass

I ordered a pcm from overkill and this is what he said (I am putting in a S/C engine in place of my N/A on my 2005 gp) any input or advise.

This is what he said:
Only question mark on doing the swap is hooking up the boost bypass valve. I'll look through my wiring diagrams and try and find the PCM PIN for it, then I'll scan it so you know where it is. If it hooks up like the pre-gen (more than likely), you'll need to hook up the two wire connector to the PCM PIN and the other to a 12 volt source.



TIA

just dont hook it up at all. mine is run with one vacuum line, thats it. you need to leave the lower nipple open to the atmosphere.
