just got my 4dr. mega cab 4x4 dually, it has the 6.7 diesel in it, i'm looking for a programmer,chip to install, i'm not wanting to make many mods,maybe a air filter, cat back exhaust, what programmer should i consider? thanks for any input

 

There aren't a lot of choices right now... I'd be patient and let the testing settle out some so you have more choices and will be able to sort out some practical feedback.
