Question to Diablo owners I just installed a Diablo handheld tune on Camaro. I have heard of people talking about 91 vs 93 octane tunes that are available on these units, but the only option I was given was a "performance tune". There was no option to install any sort of different canned tune.
Do I have to go in and use the "modify tune" options to adjust for 91 octane, or is there no option available like that for my car? I am using part #7198.
Reason I want to know is that there is only 91 octane around where I live.
Thanks.
