I just got My Max Energy 2.0 and I was looking for suggestions on tunes for my truck. I've got a 4" lift with 33" Trail Grapplers. I tow 2 atvs about twice a month so I need to figure out a tune for towing also. Any suggestions would be helpful.

If you tow a lot the 93 octane tune would work best and then you would want to firm up the shift a little to keep the clutches from slipping.
The 87 tune wont add any power but makes it more drivable. 25% shift firmness is a pretty subtle difference but would be better on the transmission than stock. You might go with 50% for towing
The thing is that you can play around with it until you get what you like.
Just enter your tire size for a speedometer correction or use a GPS if you want real accuracy.
