Hallman pro rx question??
i have install a hallman pro i have problems with the boost. In which gear sould i set it. i want to set it to 20 psi. i only receive those psi in 5 gear in 3 and 4 gear i recieve about 18. Is that normal? i hook that MBC between the intake and the wastegate.
should be attached to a boost source (ie. turbo, BOV) and then the other to the wastegate like you already have...try that first. there is a hole write up on the install of the hallman...check it out.

also, change the spring...cause it wont hold up to 19 psi..i had my hallman mbc 2 weeks ago..and i couldnt get the boost to go up...so i changed the spring to heavy one...
and it works....
but i still get boost tapper....i might have to change the bov...
