Diablo Tune is 93 tune. What car are we talking about? Some cars have CAI tunes, some don't.
That might help,lol. It's an 06 Charger R/T.
VAS answered on the Chargerforum. I understand it's a 93 octane tune and must not have a CAI provision. I'd assume it's a little richer anyway to stave off knock. Thanks for the help and your time.
