boost controller broken?, greddy profec spec B Options

[brianforster]

ok so today i finally got around to installin' my boost controller.

It is hooked up as so:
We used the nipple to the VERY right of the intake manifold. It was blocked off up until this point. I made sure it was indeed a vacuum port by blowing in it and air went through the intake system.
This hose is hooked up directly to the profec's headunit.

We hooked up the solenoid as so:
"IN"is hooked up from the compressor housing, and "out" is going to the wastegate. The other port on the wastegate (the one for the factory boost controler?(TDIS brian says)) is not hooked up.

THis is not Brianforster, this is his buddy so I apologize, but I dont know everything about how your silly turbos work.

At first, we were getting good boost playing with the knobs and making good pressure. We would hit 15 psi, and then it would slowly lose pressure till about 12 or 13. We played more until but we couldn't get any more out of it(still peaking at 15 and dropping). Then, it stopped working. It would make the factory 7-8 and nothing more. We parked it, checked our connections and hoses, and drove it again. It worked for the first two pulls, but afterwards, same stock boost.

I have two thoughts on this problem. One is that maybe I hooked up the solenioid backwards, I will go check.
Two, should the wastegate get the compressor housing pressure and then we hook the soleoid "in" to another port and the "out" to the blocked off hose on the wastegate, or is it all just broken?

TY

tvis = toyoa variable induction system. this is on the intake manifold. it opens up 4 extra runners to get more air into the motor.

tvsv = turbo vac switching valve. this is a factory boost controler. the WG spring is set to 7psi. when the ecu decides its safe to do so, it engages the tvsv to give more boost (around 10-11psi). if you want to install a boost controler, you have to disable this by disconnecting the hose that goes to it and caping it. you should leave the harness plug connected to it tho.

if you are only getting 4psi, then there is something wrong. either your wg is stuck on the after market dp, or you have a boost leak, or something going on. on a healty 3s, there is no way to only run 4psi.

enough withthe 4 psi the DP is NOT the issue. ive grinded open, installed it, ran it for a few hunded miles. took it off when i did my FMIC install. there are no signs of the WG hitting it. i do have a ****ty idle, which does give me a bad vac at idle. vac while driveing when i let off goes to 20-21vac
