Are you running the original unported 9.8 cm turbine housing on your turbo?

Did you install a new O2 housing recently along with the Forge WGA? I was thinking that several people have reported the need to port the crossover opening in some poor examples of the EBay O2 housing to help control creep.

WOOHOO, OVerboost issue is resolved. I am still running the stock hotside and I have the MR O2 but not installed yet. I will get a picture and description in a bit of what the issue was. So far it is great. Now i need to resetup the MBC. running just the WG was about 19 PSI from peak to redline. thanks for everyones input.

Good to hear that you resolved the issue. 19# on just the gate is fine and then use your MBC from 19# on up to peak boost level.

So, as the title said, first it was boost creep. i was trying to adjust the WGA pretension and the next test session I has overboost....I decided I was going to try and swap the stocker back in. While removing the Forge unit, I found the vaccum nipple was loose. In red circle of picture. It screws into the body on my unit. Must have come loose during the install when I had the vaccum hose connected and was trying to route it. I tightened it and went for another test. Overboost gone. Now i will have to test to see if the creep is gone.
