Yea, mine is my "own" twist on his package. Typically he does this setup with an upper and lower pulley and you run it on E. He gives you a 93 octane "drive around" tune for you to use if you can't find E. Me and a handful of others retain the 93 WOT tune as well as the E tunes. I figured out a way to only have to change the ring, and not the belt, so switching takes about 10-15 mins if needed.
