I posted a thread in the fall about my waste gates sticking wide open while driving. Since then I replaced all vacuum lines and had the turbos/waste gates replaced under warranty (while car was FBO may I add :D) BUTTTT the problem has yet to be solved.
Typically when cruising on the highway around 3000 rpm, slight load on the car and boosting about 3psi my waste gates will just open up 100%. The exhaust note of the car gets very loud and unless I give it a great amount of throttle the car will stay in this state. I attached a link for datazap. I managed to log the car when this happened. The car does it with JB4 which I had previously, stock and Cobb so the tune is not to blame but I feel the DME is telling them to open.
I'm just learning to read these logs so what I'm saying may sound crazy. Load requested and load target are spot on. Up until the waste gates open the boost requested is actually zero but my car is making 2-3. When you watch the WGDC the DME is telling my waste gates to open. I'm lost on why it would do this.

I could really use some guidance.
Currently I'm getting e-tuned by jake from ptf. He's doing a great job but I don't want to keep bugging him about my waste gates. I paid him to tune a working car not a broken one.
Quick explanation about my car-
2008 135i n54 IJEOS
Catless dp, berk mids, axelback, Cpe charge pipe w/tial bov, dci, cobb ap and ETS fmic.
Full throttle the car runs great. Logs look good and never any codes thrown.
I replaced the spark plugs, cleaned intake valves, replaced wg solenoids, vacuum lines, turbos and waste gates.
ANY HELP WOULD BE AWSOME. I want to continue tuning with Jake ASAP but the waste gates opening are making me crazy.
Thank You
