Haha I see. I'll chem them out. Not sure I would prob just keep it on a lower setting for fuel economy but what do you suggest? Would 35s look too small with 6 inch lift?

35s and a 6" lift may look small, but if you do not like it you can take the lift out and throw in a leveling kit and still clear them :tu:
But if you do not want an adjustable on the fly I would say a smarty, if you like the idea of changing it while driving down the road I would say an edge juice with attitude and a cts monitor to keep an eye on parameters and have a touch screen.

Yeah your right I think 35s are the way to go. I'll look into both of those tuners thanks for the help

One more question. What other upgrades to the truck would you recommend Especially for fuel economy? I heard if you use a chip it's recommended to use a bigger exaust

I would recommend a cold air intake, an exhaust system (4").
It depends how far you want to take it. An intake horn, bigger charge air piping, and a new charge air cooler (intercooler) would also help get a better supply of cool dence air, but the most people stick with the top 3 for Mileage :tu:

Sweet thanks got my smarty jr programmer works awesome so far won't be cranking it up too much though. Just a question on leveling kits do all of them put strain on your front end parts or are certain ones better? Figured I would get it put on by same guy taking out my lift

A leveling kit is a leveling kit, keep in mind bump steer. A 2-1/2" leveling kit should be accompanied by a 2" drop pitman arm. It will prolong the life of the draglink, and reduce bump steer. Unfortunately with the heavy cummins and any lift it will put some added wear on the ball joints. I just buy the cheap ones and swap them once a year. Timkin wheel bearing have always treated me very well. Good quality and a good warranty.

Play with the smarty and have some fun with it :c:

Okay lift kit puts strain on ball joints too don't they? My truck vibrates when I get up to about 110 km/hr one guy told me it's main driveshaft cause of the angle it's at with the lift another guy told me it's the front driveshaft cause it hasn't been greased at each oil change even though there is a sticker under the hood that says to do that.

Yes. It's very hard to say without having all the specs on the lift. Is it a cheap lift? Who makes it. What does it contain (springs, blocks, ect.) once that information is out in the open it will be easier to diag
Yes all of them hurt balljoints, exponentially as the lift gets larger

Alright it's a 6 inch bolt on super lift.
