Difference between the Diablo Tune and the 91 Octane Tune
Posted: Sun Jul 15, 2007 12:17 pm
I have a Predator U7191 and was wondering what exactly was the difference between the normal Diablo Tune, which states on the website is for premium gas, and the 91 Octane Tune. Correct me if I'm wrong, but isn't 91 octane premium gas? So... I'm a little confused. Any help is appreciated. Thanks!
