Try using the Cobb HWGDC map that they have if you are not able to hit target boost. You may also have to adjust the WG arm a couple turns to get where you need to be. Let me know if you need some more help

10 psi target is really low for a stage 2 map. why is the target so low to begin with. with an open downpipe its really easy to surpass that low of a target. also your dam is at .5, in a happy with no knock it should be 1.0. your car apparently does not like that map.

That's because we don't have separate maps like the 08+.

Your car hasn't learned to use 100% of the timing advance yet. That may be why you are targeting such a low boost target. Drive around normal for a few days, and see if it doesn't learn to 1.0. If it does, run another datalog and see if your targets have changed.

On a side note, is this a new AP? Is it on the latest firmware? You can update it via the AP manager.

How long had you driven on the flash before pulling those datalogs?

3 days driven on map before logs were made
the ap is a year old and has been updated before map was flashed

Something is DEFINITELY wrong here. Your DAM should have learned to 1 already, and your boost targets are about 5psi too low.

I'm going to take a stab and say that the engine knocked causing DAM to fall off and disabled the boost control system.

Try flashing a less aggressive map.

Edit: I see you are already on the least aggressive of maps. I think its time to reflash and see if the ECU is learning or if DAM is just staying at .5

Flash back to stock and then back to your ACN91 map. Do a bunch of city driving today and tomorrow, and monitor your DAM. If it learns up to 1, pull a datalog.

Also monitor your boost targets.
