On smaller turbos the gain is smaller. On larger laggier setups no lift shifting (NLTS) or "speed shifting" (in many automotive circles "power shifting" implies the clutch is not used) can be a huge benefit. On my 2g with the 2.4 and T67 I picked up nearly a full second by NLTSing. But that's an extreme case, it was a pretty laggy setup, and I'm not the world's fastest shifter 
On the stock EVO turbo my boost generally will not fall below 15 psi between gears regradless of how long I take to shift, with a 5500-6000 rpm shift limiter.
The best way to do this is to use something that cuts the power based on the upper clutch switch. DSMlink and AEM do this, and others as well I'm sure. Since the Exedy twin engages at about the midpoint of the total pedal travel, the clutch is fullt re-engaged before the switch is made and the ECU puts the power back in. EXTREMELY smooth shifts when NLTSing, much smoother than when I lift. And the Exedy twin seems to do it even more smoothly than the typical single sprung disc type clutches shifted for me. No clunking, no banging, nothing eventful at all. I love it, personally.
