So as you can see the stock boosting is normal but with the GIAC in it gets all cooky. Thats also when the O2 doesn't read. So I'm beginning to agree that it's looking like the problem is from the flash. It's my 3rd re-flash though...

Oh, and that's really low boost for what im supposed to be getting.

Fixed via pressure testing (thanks ryan/stoney).

The culprit:




Had a samco boot conveniently in the trunk so I popped that in and...




Still boosting low and all codes are still present, but the curve it solid which is a step in the right direction.

Haven't you had a boost leak since the beginning of time. It seriously seemed like you had one months ago, was that it?

yeah thats the beauty of the 2.7t...

I'm not sure if I have a leak per say anymore, but I am boosting about 5psi lower than I should...
The evap or the O2 code could be causing that. Im going to cop Chris' O2 sensor sometime this week(end) and throw it in my car to see if it fixed anything. As far as the evap code, still workin' on tracking that one down....
