Vac lines are easy... leaving everything stock works fine, run one of them to the bottom of the wastegate for your boost control.

They just use regular boost reference to go straight to the top of the wastegate with the regulator in line.

I'm running a turbo smart boost controller and can't adjust boost. I'm sure I might have the boost controller hooked up wrong.

My vacuum goes like this:
Bottom wastegate to MBC
MBC to T fitting
BOV to T fitting
Top waste gate to T fitting
T fitting out to top port of M90 case

In other words everything is connected to the t fitting then goes to the top port of the M90 case. Doesn't matter how many clicks I do on the MBC it doesn't go above wastegate spring.

Any suggestions being stuck on 11 PSI sucks

It's a CT kit...
