For economy id go with smarty jr. My buddy did the h & s and gets nowhere near the fuel mileage im getting even at similar settings

 

Mine gets about 15 in town and about 17 on the highway with h&s and I'm on a 6" lift and 37s I'm very impressed with it.

And as far as smarty not leaving a footprint.....

A few months back efI live was having a problem with crashing ECMs after they'd been previously tuned with smarty because smarty did not put all the files back correctly when ECM was returned to a stock tune with the smarty resulting in double tuned files so to speak. That's the main reason I'm not a 2010+ smarty fan.

Any tuner is going to leave a footprint just by their very nature.. a tuner flashes the ECM the dealer has a record of how many times they flash the ECM and if the number of flashes that the truck is showing doesn't jive with the number that the dealer showing it will cause a flagged warranty because the ECM has been flashed by somebody other than Dodge.

Bottom line if you can't afford to lose your warranty do not tune the truck because no matter what you do they will be able to find out that you had a tuner or whatever on it and your warranty is kaput

This is correct. They can't tell what you're doing in there, but they can see how many times the ECM has been flashed.

So if there is 2 factory flashes and the ECM has seen 10, you're boned.

 

How at forgetting an actual tuner and going with a fuel injection fouler ? Which plugs into the fuel harness leaves no trace in the computer and steinbauer performance and TsPerformance make model that that work well lots of guys stack these with other tuner types but its not nessecarry as they can add 50-100 house power by themselves . A good Towing option.
