I have a 2015 ram 2500 did a egr delete ,4in turbo back exhaust raceme ultra tuner.I really like the tuner work's great lots of power the Cummins is awake now.

 

I just deleted about a month ago - wish I had done it sooner! I also went with the RaceMe Ultra. Run it on stock power.

 

what kind of fuel mileage do you get on that tune.I got 18 mpg on the +120 got 16 on the +150 with quick spool going to try +60 next .it's hard to run on the +60 after playing with the last tune.All my driving is a mix of highway in town and idling + playing around

 

I at one point hit 19.5, but that was all interstate, not towing, on 30 hp tune. Stock tune, mix of highway/city, getting 16. Before I deleted, was lucky to get 13.
