What can I say....I GOTA CUMMINS!! Finally took the time to join. I have read a lot of stuff on this forum researching stuff on my truck. I currently Have a 2015 Ram 2500 Quad Cab Laramie. Truck is Lifted with 37/13.50R24 wheels and Tires, Fully deleted with MM3 tuner, Amp Power steps, 4:10 gears and many other upgrades and always finding something else to do to it. I haven't been the happiest with my tunes and wasn't aware of Double R Diesel when I got my tuner. Hoping in the near Future To Purchase Tunes from Double R Diesel!!
