4/3/2009 Update:
Took the car back for some 91 octane love.
Got some good news and some bad news.
The only change from my last tune was that I swapped out the MilSpec ported Invidia O2/Skunk2 Dp for a MAP Integrated O2/DP. When we installed the MAP piece last week, I immediately noticed creep/spiking issues that didn't exists before so I advised my tuner when I dropped it off this week that this may be an issue.
So today it went on the dyno and there is definitely creep...in fact it’s pretty bad. After playing with it for a few hours, it just wouldn't go away so we decided to stop for now and try a few fixes before proceeding.
The results at 22 psi, creeping to between 27-28 were 464.64/364.63.
Once we get the creep issue resolved I would expect to see a 20-30ftlb increase in torque and a 15-20whp drop. So a rough guess of 445-450whp/385-390ftlbs on 91 octane. Pretty damn good if you ask me.

Checked the WGA and that isn't it 
My belief is that the gasket may be the culprit. While I understand it separating the two holes, the small diamter of each concerns me somewhat. I am going to release some of the preload we were using for the old setup and hope that this works, since I am not into swapping it out again. If that doesn't work, then Ill remove it, have the gasket ported/cut out significantly, and then try again

I didn't do a back to back comparison since I was running the other o2 housing/Dp combo on E85 and this one was on 91 octane. If I cannot get this to stop creeping, then I will reinstall the other combo and then Ill have a back to back
