SO my MBC from eBay (eBay yay) came in. I search some threads on it to find out how to install it. I didnt find what i was looking for but i got the idea on how it works. So after i put it on i took it out for a drive fully closed and my boost jump up to 10psi real fast and i back off right away (because im on Vortech 12:1 with stcok 1.6 injectors). Then i pulled over and opened it and drove it again and got the same results. I thought to myself maybe i installed it wrong. Well i got a fuel pressure gauge and im going to install my 305cc with vortech and see how it holds at 10psi.

 

um yes thats wrong. Idk what the little red peice is (T fitting?) but the boost controller should be spliced into the blue line comeing from the compressor on the turbo - boost controller - then wastegate.

Get rid of the little red t fitting.

 

now that I look at it more I cant tell how you did it, there is a linecomeing off the intake pipe.

dude, its easy. Take the blue line comeing from the turbo, plug it into the arrowed nipple on the boost controller, then take the other nipple on the boost controller, and plug it into the wastegate using another rubber hose.

 

Hooking the MBC up to the turbo's intake is worthless, there is no boost signal there.
Cardriver's instructions are correct.

 

don't feel to bad, when i bot my FC that's how the guy had it set up. here's how it should look

 

Alright I removed the 'T' fitting and did what cardriverx said and it fixed the problem. Thanks For the help!!

 

beware of that T-fitting if it's the kind with the ball bearing inside. I had one installed set up 100% correctly and the spring in the t-fitting was so strong, I spiked upto ~20psi a few times before just removing it's ball and spring. The main unit works pretty good though.
