Which is the a recommended direction? I know the 3 is newer than the 2, but is it better more versital, provide more features.

This is for an 11 daily driver 5.7, quad cab, 6 speed with 3.55s.

Thanks.

Found a used I3 for sale that according to the Diablo website fits my truck.

Turns out when I got it in the mail it's a model 8320 R which is the platinum 8300 inline i3 and a pcm swap for the original purchaser.

Obviously I only got the 8300, plugged it in the truck did about 25 minutes worth of updates then installed the 91 octane tune.

Not certain I can tell the difference as I have not had the truck out for any great distance, just a quick drive to the store and back.

Any recommendations as to which parameters to modify from the 91 octane tune?

I want to drive it this way for a few days before getting a custom tune.
