Update about making only 6 psi last night....
After clamping off the bottom hose of the N75 valve (basically disconnecting the wastegate) the car was making boost fine. Vag logs showed that the car was calling for full boost but I was not getting it. The N75 valve went bad. After messing with it a little while I was able to get it to make 10 psi. Need to order a new N75. Anyone know the part number for it and price?

You can use one of these.

Stay with the stock N75 if you want your turbos to survive. --->
The N75 is electrically controlled by the ECU, and carefully calibrated to avoid over-boost damage. Screwing with the N75 may mask other problems, but is can cost you.
