The Problem with a superchargerkit, without intercooling, is the hot air which is terrible for the engine and kills all boosts-gains becouse the engine is pinging and the ecu retards the ignition ...
I didn't feel anything noticeably different, but I changed to the 9psi soon after I added it. My IAT did go down from 120-150 max to 70-80 deg fah when spraying, which was pretty awesome.

btw LOVED the snow performance kit, used my windshield fluid wiper bottle as a reservoir and monitored my intake air temps (IAT) with an ODB2 reader (scangauge II)

So yes, it REALLY allows for more HP. It doesn't produce it alone, but allows for significant alterations to a tune which will make more power.
