2011 Silverado 5.3 - No 91 Octance Tune

[frank5266]

I was wondering if I just missed an update or something because my trinity does not have the option to select a 91 octane tune. It gives me the option to select an 87 octane tune or a Diablo Tune. Is there a solution?

those are the only tunes available for trucks... the Diablo Tune which is for 91/93 octane, and the 87 Octane Tune...

if you use 91 octane gas in your truck, then use the Diablo Tune...


and for even more giddy-up, get a custom tune done for it by a diablosport CMR custom tuner, like me...

Thanks for the clarification. I was already planning on getting ahold of you once the holidays are over. I hear good things about your tunes.
