Cherry Posted April 18, 2015 Share Posted April 18, 2015 It depends what you've already been using, I think if you change fuel you have to retune your engine? Quote Link to comment Share on other sites More sharing options...
Shudson Posted April 18, 2015 Share Posted April 18, 2015 The number represents the % of nitromethane. Which is better depends on your engine. 1 Quote Link to comment Share on other sites More sharing options...
