do you need the stock boost solenoid if you have a manual boost controller

no you just pull the van lines off the turbo and bypass it. mine's still there pluged into the harness though. just doesn't do anything. not sure if it'll turn on the check engine light or not with it unpluged

Haven't we ALL heard this
I unplugged mine and it made the check engine light come on.
I then left it plugged into the harness with no vacuum lines on it. However, the computer still knew it wasn't controling boost.
When I pulled the codes it came up. However, it did NOT make the check engine light come on. This is in my '91 TII.

Few things here -
The stock boost control solenoid is good in one application - on a stock car. When you start modifying the car, it will quickly run away with the boost, giving you some dangerous overboost conditions.
The ECU doesn't care if it's plugged in or not - it will store a code, but will not flag a check engine light, and the car will not run odd or go into any failsafe mode.
Even if you don't have a boost controller, if you've opened up your intake/exhaust, disable that sucker.

One of the lines goes to the turbo inlet duct, and the other goes to the metal hardline on the turbo.
Easiest way is to pull the two lines from the boost controller and plug them. Best way is to plug the hole in the inlet duct and the one going to the wastegate actuator.
If you splice the two lines at the boost controller together, you're gonna have some serious boost.

your boost will drop from 8psi to 5psi when you disabble it. but then it'll most likey creep higher.
the first thing I did was disabble mine before my exhaast went on. so I was getting 5psi slowly creeping to 9-10. adding a manual boost controler set to 9-10 made the car so much better
but don't use the stock one with a modded car. exspecially when using a FCD. ECU controls the stock boost controller. FCD makes the ECU see less then 8psi or so. so I bet the controller never fully cuts out causing more creep.
