I posted a while back about this... The answer is complex. Where I found it to offer an advantage was not so much between shifts (6MT), but on and off the gas in the same gear.
What I mean is if you're waiting to overtake, for example, and you're already in the appropriate gear, when you floor it, the boost pressure will already be built and held and you'll surge forward.
I'm still investigating it, and will post a new thread about it soon, but I think what we all feel is turbo lag between shifts (6MT) is actually the DME not allowing boost to build for some reason. The DV+ (and alternatives) don't help with this as all because boost is lowered by the waste gate and not the diverter valve.
