Race fuel = slower ignition. (Allows more timing advance or compression or boost. None of which you have.)

Best times = Good air (High barometric pressure), good traction, little incremental changes, and practice, practice, practice.

In any endeavor which I begin at (and suck at!), I always simply watch and ask and chip away at things. In time, all of a sudden you 'get it'.

Good luck!
