I'll have a look for diagrams as someone else already put boost controller in but not sure if it's done right

Would normally go: (as you'll see in the thread mezje linked)

Barb on plastic elbow (pre throttle) -> tee to solenoid and metal line that splits to each turbo -> wastegate on each turbo.
other port of the OEM solenoid connects to just after the air filter/MAF to bleed air.


Trace it out and can probably advise if it's right or not. but MBC is your ticket to hitting boost cut :)

FYI, the hose with the red end painted has a restrictor in it. See if any of the hoses have a red end painted.

If it's a manual boost controller in the engine bay it's pretty hit and miss. As BCX stated they tend to overboost and aren't reliable in holding any steady boost.
If you're not going to be running an electronic boost controller perhaps think about sticking to the factory set up.

Thanks for that, that's pretty much what the diagram I looked at last night says. Yea it's already overboosting and boost cutting coz last owner put MBC in and it's been seized right open so it just free boosts till it hits boost cut. Want to replace it with one that's working and wind it back to around 10psi.
