He tows our dump trailer, that's a few thousand pounds empty, loaded down with building materials with ease. And on the weekends he tows his enclosed trailer w/ the drag boat, ect in it...that's a 12k # package. He's towed that from OR to AZ and back with ease.

I'm not saying it's the best...just saying he's happy with it !

PPE is one of them I am considering. I think it will be that or EFI live. Truck is getting serviced today, fixing some little issues, and getting ready for its first trip down to GG Dallas next weekend. I checked mileage again yesterday and got 15mpg bone stock hand calculated. 18 or better should be reachable with upgrades. I know lots of guys picking up 3-5 mpg with tuning alone.

Mike, my cousin is getting 19-20 mpg on the freeway...slightly less mixed driving. And he gets in the teens towing. His towing mpg is what I get non-towing! I really need a diesel with all the driving I do! FWIW, he's only on setting #2 out of 4. He raced his dad (I was in the truck) he has a '03 6.0L Silverado 4x4 before the tune and they were pretty even....after the tune the diesel ran from him! I haven't always been a fan of diesels....but now that I've been around them more and I tow quite a bit these days I really see the need for them!

I preferred EFI Live because I did my own tuning. Dan at PPE is very sharp. His tunes are more money, but they do what they're supposed to.
