Problem with Turbo Xs mbc

[SpoolN]

When i put it on today i was boosting t 20 psi no matter how i adjusted it.................................. I need to know what lines to splice it into. Right now going into my wastegate there is 2 lines going into it for some reason. ......

Cap off the tube coming out of the compressor and only use the line out of the wastegate actuator.

Right now there is a line tee'd off my bov that is then teed into the line running to the wastegate. When I took the line that was teed off of my bov out and pluged all the holes the car was running 20+. The only way right now my car runs a consistant amount of boost is when the line from the bov is hooked up to the wastegate. When I took my car to the local mits. dealership this is how they ran it. What line is usually hooked up to the wastegate stock?

That line is T'd that runs into the stock BCS, from both the compressor and the wastegate actuator. Aftermarket boost controllers only use the line from the wastegate, and the line from the blow-off valve. I don't remember if its Turbo XS or not, but one of them needs the vacuum lines run backwards compared to most other MBCs. The T'd line from the BOV runs straight into the MBC, and the line from the wastegate goes straight into MBC also. Disconnect the line from the intake to the BCS, since you won't need it anymore. Hope that helps.
