Hey all, this weekend I switched intake manifolds to the BRM one, got new fuel injectors, and took my EGR cooler off and replaced it with a metal pipe. Now I went to turn my car on and I've got no boost but no CEL. Boost gauge reads a vacuum of 1psi in fact.

Did you move any of the vac lines? You may have accidentally disconnected one.

So. You say you replaced your egr cooler with a metal pipe, what exactly do you mean a pipe? You'll get low boost if you have an exhaust leak between the egr supply bung and the valve.

Seems like the only vac line undone was the one going to my airbox, everything else seemed fine
If you plugged it that may be the problem.
The system needs to vent vacuum as needed.

Not sure but I think when I closed that hose the car stalled, but it may have caused the ASV to close.

Was a long time ago.
