I found that it's excellent at preventing detonation and thus maintaining high boost levels even on hot days. When I first installed it, I even noticed a kick in the seat of the pants after it had been injecting for a few seconds, which corresponded to a jump of about 0.05-0.1 volts on the Air/Fuel gauge. Still get the slight kick, but I have since raised the max boost, so it's not as pronounced.

As for 85turbo, I don't agree that H2O injection (or washer fluid in my case - 20/80% methanol/water) is worse on cold humid days. On normal days, say temps in the 50-60F range, I was maxing at 17-18 psi. I came home last night after Dyno Daze, and temps were in the upper 30s and it was foggy out - I hit just over 19 psi. What's bad about that? Isn't slowing down the burn just what a higher octane fuel does for you?

I'll agree to the sentiment that it isn't magic, but I do believe it serves it's purpose extremely well - preventing detonation. For those of us who can only obtain 92 octane fuel and live at sea level, asking for more than 15 psi sustained is a tall order.
