93 legacy loosing power

[turbolegacy93]

My 93 ss is running top mount, greddy bov, manual boost and open downpipe(stock). It tuns perfectly fine until it starts to build boost once it goes past the 0 on the boost gauge. You can't get on it at all. Have any of you ha this problem? There is no cel.

Usually if you have this kind of problem it's related to a pressure sensor or something not right with the electronics.

You may want to try running the "active" diagnostics with the green connectors

Sounds like it also might be a vacuum leak, I would check all of your vacuum lines. Do an active diagnostics check and post back an codes you might get.

Thanks for the impute guys! And I checked the black connections and it has two long flashes followed by two short flashes, so is that a 22 ( knock sensor ) I haven done the green connectors yet.

Ok, yeah check the green connectors, see if anything comes up, clear the codes and see what, if anything comes back.
