In all your a logs except the first one you are over boosting. Might want to try the lwg map.

I would try the super low wastegate (SLWG) version of the map. Boost is not tapering as fast as it should at higher RPM - this could be a case of boost creep, but we'll see what the SLWG log looks like (if you can get one safely). What downpipe do you have and what are the outside temps with these logs?

Boost creep can be more likely with the divorced wg downpipes, although can still happen with bellmouth style downpipes. I would give the SLWG map a try and we'll see what happens. You want to try to get a higher RPM run (near redline), if you can do so safely.

The SLWG mapping dropped your peak boost levels, but the car is still building too much boost from 5000+ RPM. Your car may be suffering from boost creep.

There's one more test we can do to see if we can tune out that boost creep. Try doing a realtime map change to the Economy map and datalog one 3rd gear pull. If your car is able to maintain 8 - 12 psi at redline then we may be able to tune it out. If your car still creeps up to 14 - 15 psi at redline then you have true boost creep.
