3.3TT HELP!!! No Boost!!

[ChiTownStinger]

Hey guys! I ran the car on a dyno Thursday and now I don’t get any boost! I checked all of the intercooler couplings and they’re good. I did notice though that my TurboXS BOV’s are stuck open, thus causing a leak. I can unhook the vacuum line and then they close, but after starting the car they stay open. All of the vacuum lines look good, so I’m kinda stumped here. Any ideas??

Are the rubber caps still on the diverter ports of the intake pipes? Make sure those are tight.

100% your valves. Just swap the stock back on and maybe blast the valves with some compressed air

What valves are you talking about?

What valves are you talking about?

Blow-off valves. If they're sticking open, they're just venting all boost back to the inlet.

The pistons are working properly, I think the issue is the solenoid.

Just take them off.

Stock valves didn’t fix the issue.

Where does the vacuum line you mentioned onnect to? You mentioned that disconnecting it means the BOVs close fine?

I am having similar problem on 2.0 car. Fitted hks blow of valve and the car goes into limp mode.

We've connected hks blow off valve using standard vacuum lines.
