If you set the DTA demand curve at a higher boost pressure (ie 1,6 bar at 2000rpm) than the engine can attain then the controller will wind up, so then it is to slow to open the valve which causes the overboost.

Ah, yes, I misundestood 
See your point now and I agree, after two years of trying, I think a aftermarket ebc would be best also.
