I haven't gotten the vacuum lines routed to the filter yet, but I moved the one for the BC sensor to the rear of the UIM, along with the one for the boost gauge. The line from the side of the wastegate was already moved to the front of the UIM near the TB already.
So far I've only gotten about 10-13psi when it's set to 15psi.
I've forgotten to mention I don't have some things on the EBC set up, I have it set up according to Rob Robinette's directions, aside from not using .65 (9psi) as the boost setting, but 10 and 15psi on setting A and B respectively.
