Great kit
Easy to install and everything worked out great. Wish I would have done it sooner. Mileage increased from 12.5 to 18 empty. Also very happy with the performance gains for towing heavy

Best thing that happened to that truck
As I’m sure you know that model year is plagued with issues around pollution control components on the 6.7 Cummins. On top of that everything is extremely expensive. The power increase on the lowest setting is remarkable. Add the fuel mileage increase , I’m kicking myself for not doing this years ago. Finally something that lives up to the hype. Thanks and kudos to your whole organization.

Wish I did it sooner
Easy way for better mileage , power and smiles.. I did it to make up for the increase in diesel prices here in California... with boost tubes and monster ram ... I now average overall city and highway lowest 17.7 mpg to 19 Just cruising freeway average 21- 22.7,,, have seen 23.5 once but before it was 11.9 average city highway and a best of 14.6 highway ... 37" tires 4.10 gears 3500 srw
