Best tune for MPG on 2005 Chevy Silverado 5.3? I3 INTUNE

Post by Puna2k »

Hello everyone, I'm new to the Forum and new to my Diablo I3 tuner. I was wondering what tune would be best for MPG on my truck? In the tune options I have 87 octane 91 + 93 but did not see an MPG boost tune, it's ghosted. Out of the ones that I have which would be best for the mpg, and I'm not a Leadfoot when driving.
Also every time I connect my tuner via Wi-Fi or through USB to the update agent there is always an new update available. When I update it there's always another update right after it. Is there actually a new update or am I just updating the same files every time?
Thanks in advance

there is no MPG Boost tune for that old truck.... that tune is only available for newer vehicles that have AFM/DOD....

So I assume the 93 octane tune will give you my best MPG since it burns more efficiently.
