Thanks trailer, race car are & all my race junk are over 8K so ill switch to the tow tune. Whats the difference of the 2 tunes other than the obvious HP & TQ numbers?

I dont have an EGT gauge do you suggest I change to the tow tune for the long haul?

I just bought a 2006 5.9 3500 Dodge Ram 2WD long bed with 61k miles & 410 rear end. Truck belonged to a retired gentleman & its flawless so i am sure it was cared for very well.

I installed a predator performance tune last week & i am loving the added power & fuel economy. 28-29mpg on the highway ...
