Re: (itr206)
you need to have one of the vacuum ports on the solenoid box going to the waste gate ...and one to a direct vacuum source off the manifold
that is why it is not working
remember to run it low to start
Good luck

ok the way you had the wg before , leave it the same way , now all you do is take that open bottom port and put the solenoids in line with that same vac source your bottom wg port is feeding to, as far as the controller box port that goes to a direct vac source too , ie fpr vac source.

Re: (TURBO B)
u need to buy a 2 plastic "T" fitting at autozone($0.50) cut the vac line from the profecB to the black box insert the "T" fitting in between them and w/ the third nipple exposed connect another vac line to any other vac line on the intake manifold using the other "T"

Re: (drLazy)
ok basically ur wastegate needs pressure form the intake manifold to open and close no matter if u have a controller or not. the controller is just a valve that goes between the vac line from ur wastegate to the intake manifold that u had before u bought the controler. its like a closed loop: wastegate<black box<profecB<back to the intake manifold. but u have it hooked up in a open loop: wastgate<black box<profecB<???? this is where u need to T off to a vac line on the intake manifold, just go to autozone ask them for 2 plastic T fittings and it should all make sense to u, so basically u need to route a vac line from any intake mani source (w/ a T) to the vac line form profecB to black box (w/ the other T)
