So I found a place locally that has race gas 104 unleaded for 6 something a gallon. I want to do some testing with it before the GM bash in Ohio coming up in 3 weeks. What sort of changes can you make to take advantage of it?

I know obviously timing but I'm around 25 right now with no knock, I was told previously in other threads that anything more is just beating the @!#$ out of the bottom end? How much timing is too much under WOT?

Any other changes that can be made? Leaner AFR perhaps?

the tune im working on for my setup with race gas has more advanced timing and less fuel.
