Hey guys I am back to 10 psi. I hooked up the mbc and know for a fact i did it right because i turned it up and it went to 17psi at one point because i just kept on turning it. I started slowly of course. then after that i turned it up again and it went back down to 10psi. it never went back up. i replaced the spring to the harder oneturned it up all the way and still at 10psi. what can it be??????

 

inspect your vaccum lines. did you ziptie all the ends?

 

ok. ill chk those and i didnt ziptie those ends. anything else i should check for???

 

Check all the MBC connections and IC connections. It sounds like something popped off.

You have to secure each connection in the boost system - you can't just slide the hoses over the nipples.
