Pump Gas, CR, Octane Booster?
Whats the highest CR I can run before I have to start looking at race gas?
I hope there wasnt already a thread for this...if there is can you hit me with a link? This is really bugging me and I want to make sure I won't need to go with a higher octane fuel.
Also, what are some PROVEN octane boosters out there and how far do they bring it up?
