2019 3500HD

[drucker]

My father-in-law would like to get better mpg with his diesel 3500HD dually with service bed.  What products will help this the most? I figured programmer and air intake but don't know which are better.

What year is it? if its 2016 or older, its cheap to delete them and run a conservative tune that will improve fuel mileage a fair amount. If its an L5P (2017+), it's pricey and not as many options

 

edit; sorry just noticed in the title of the thread that its a 2019. Other than deleting and tuning, most people have great results from the Banks Derringer products.

My strongest suggestion is to go with Banks. I have the derringer, iDash, and the intake. I’ve had nothing but positive interactions with their customer service and their products. Mileage went up almost instantly
