Re: Fuel?

lol I run 93 everyday .. but honestly for you to see any gains from going to a high octane, a tune would be able to take advantage of it the best... the stock tune will just adjust for the difference.

Thank you I always put 93 for better quality anyway I knew it sounded probably like a dumb question lol just didn't know if the hemi would have any Benifets with a better octane than 93
