Need some help tuning my PFS PMS, before you all tell me to search, the search function isn't working right now for some reason... Anyway, I have a MBC installed now but want to control the boost exclusively with my PMS. What should I set the mbc to? Fully open, fully closed, 10 psi..? Thanks in advance!

 

This should be in the ECU section of this forum.

 

i would remove the mbc and replace it with a hose union or replace the entire hose. if you HAD to leave it, set it at its minimum level.
