Mine is around 11.2:1. Premium fuel is mandatory. If you go with 44's, you can possibly still run regular, if you had to. 10.2:1 is doable on regular, but premium is preferred. May as well have all of your power on tap! I went with the 38's because I wanted that extra edge and don't mind running premium fuel all the time. If I want all out, balls to the walls, I fill up with E85 and switch the tune.
