Unless your truck has a lot of mods, the race fuel is probably a waste of money. Your truck will only do so much timing advance and only has so much compression. Any octane above a certain number isn't doing much good. They say a stock Hemi will run good on 89 octane, but to make sure for racing I'd probably just run a 91 octane.
