setting joe p mbc

[timmy]

I am going to install the joe p xz tommorow. The question i have is that the black plastic screw is half way out, how do i know that the psi will not be to high when i run it. Where should the black screw be, interms of in out of the brass case...

umm... u need a boost gauge to use a MBC effectively because u dont know how boost u r running if u dont get a boost gauge ur blow that little T-25 to little pieces

I do have a boost guage , it is autometer lunar series. My question is how far out is that black screw suppoes to be>>>

well...

Back it all the way out, drive the car.

See what your boost guage says...

Work the screw in until your boost guage reaches 15psi, or whatever you want to run your car at.
