We'll be able to answer that in a couple of weeks. Mark still has my standard file and we want to do some fine tuning to the current file so will load the standard file to see what happens. I know when we were testing with the APR DP it made no difference power wise with just a DP and no tune but the graph definitely isn't as smooth. The factory wastegate control map assumes that there is the restriction of the cat straight after the turbo outlet. With the DP there isn't that restriction so you actually get boost coming on quicker then the wastegate opens and boost drops then wastegate closes and builds boost, etc. The result is that the dyno graph has a series of steps in it rather than smooth like it is standard. I would definitely recommend getting a tune done along with the DP. Mark said he could actually do something that just fixed up the wastegate actuation but once you've experienced a proper tune you definitely wouldn't want to go back.
