6.2 engine programmer

[EastTexan]

Any of you running an engine programmer on an '08+ 6.2 liter engine?

If so, what brand?

I like the Predator on my '05 Chevy 2500HD 6.0 liter, but as I underatnd the Predator for the 6.2 engine, the only options are 87 octane tune OR 93 octane tune. The 6.2 is designed to run on 91+, but can run on 87 octane in a pinch. My concern is if I used the Predator to reprogram thne 6.2 engine to the 93 octane tune and was unable to find 93 octane, it might cause problems since the engine timing advance parameters will be tweaked so far.

One thing I dislike about the Predator on my Chevy is it resets the engine hour meter to zero whenever the tune is set or altered. Maybe that is common to all tuners.
