So I have put about 7k miles on my 2015 so far, and I cannot take how stock it is, or the terrible fuel mileage.
So my question is, how much improvement will I see with the *** on tunes and a filter back exhaust?

What stock parts are you guys saying you're concerned about? I am new to the 6.7s, but had a pretty built 6.0 before and beat it pretty good for 70k miles with no issues.
Picking up a 2012 now.
