I don't think most have gone this route on the forum because the HP gain is not big enough.
You figure most superchargers, turbos are set to give 7-8 psi of boost and add 40-50% to the HP.
So given that, you might get 5-10 HP gain by using the 1 psi setup...not bad for $300
I think the 1.7 psi would be a waste because you are getting close to turbo kit territory for far less gain.

Also a turbo or S/C runs all the time, this kit is more like nitrous, on for just a few seconds.

Not sure if you watched the video but it is also VERY loud.

You can even watch it build pressure faster than a leaf blower (which some have suggested does work):
