It's chicken and egg with that and why you won't see it on custom tunes usually. DME's response to overshoot is to drop WGDC and close throttle to maintain calculated pressure in the intake manifold, but at the same time then causes an even larger build up of pressure in the chargepipe.

If you think the throttle is closing itself causing the boost mean increase, you can remap the pedal or kill the closures. It shouldn't rise as much without the closure, but pretty positive it will still rise the way things are there.

Edit: it may not a physical/electrical problem at all, maybe just a matter of environment, how you operate the pedal and the stock bin. I'll flash mine back to stock and see what it looks like.
