Yes VP octanium, Boostane and Torco actually work. My friend with a ESS supercharged S550 uses boostane. It dynod 720 with pump 93. Added boostane, same day within 30 minutes dynod it again 770. It was actually adding timing over what was commanded.
RPM has some videos of testing the VP booster.

As Draco stated all these have MMT. It coats EVERYTHING a rust orange color. Its extremely hard on o2 sensors and spark plugs. MMT will also clog your cats if you have them. If you plan on running it every now and then it wont be a big deal. But as stated those 3 are by far the best on the market. Torco will separate over time where boostane wont. VP octanium is the newest to the market but works.
