not seeing boost....help

I agree with the post above about probably a blown off hose coupler. Check all the couplers and clamps from the turbo to the intercooler to the throttle bodies. This would prevent building boost and prevent the wastegate from opening, since it only opens when it sees boost.

This however would not explain your low vacuum readings. Maybe you developed a tear/split in the vacuum line for the wastegate and boost gauge... but this would be a whole different thing. The wastegate wouldn't open and you would be overboosting like crazy and probably already be stuck on the side of the road with a puddle of oil and a bucket of strange metal parts on the street.

I'm going to stick with a blown off coupler for now until there is new information
