Need some info on how W/G & MBC work
 

Can I use a 5psi spring in the W/G and flip a mac valve on to a mbc and get 20+ psi

Would both hoses go to the bottom of the W/G and the top be vented or plugged , would the lower psi boost hose go to the bottom and the mbc go to the top of the W/G or would both hoses go to the bootom and a hose from the comp side go to the top with a regulator and a bleed valve to help set the boost at a higher psi.

I'm not sure how these work so any info would help

Thanks Mike

The manual boost controller goes between the the vacuum/boost source and the wastegate. So hook it up like the manufacturer says too with the boost controller on the middle. You probably won't be able to hit 20#'s with a 5# spring. I would try to get a 12 pound spring in there.
