wastegate or vacuum hose issue?
I've been having a boost issue for a few weeks now. I still get full psi for both turbos but it feels like somethings sticking before boost kicks in. I'll go WOT, the gauge will stop at 0, there's a mooing sort of noise and then it jumps straight to 10 psi. I have no clue what this could be and nobody i've asked so far does either. Any help would be greatly appreciated.

I had a problem like this with my FD. The coupler on my y-pipe had taken a dump and coated the side of the motor with oil and baked rubber coupler. After I fixed the leak with a new coupler I'd have sporadic loss of boost after a shift. I cleaned everything up on the side of the motor. I noticed the actuators on the turbos stuck sometimes. I cleaned them up, blasted a bunch of wd-40 on them then cleaned them down again and added some lithium grease. Problem was gone. As far as I can figure the waste gate actuator was getting stuck open making it take longer for boost to build.
