For anybody considering a tuner for their diesel truck I thought I might share some positive info with you. I had the Bullydog GT installed on my 2014 Ram , 6.7 Cummins and sorry EPA, I had the cat and muffler removed as well. There is improved throttle response, hardly have to push on the pedal and your moving. Performance wise, yes, you can go faster, need I say more. Mileage has improved as well, up from average 21 to 25 mpg on my last hwy. trip, @ 70-75mph. Brief history, the map sensor went on the truck, and of course the extended warranty that i just HAD to have when i bought the truck doesn't cover that sensor. Quoted $1300+ to replace it. Right after voicing some polite frustration to the service adviser at the stealership i said that if you don't cover this I should just get it all cut off and put a tuner on. Amazingly he agreed. Hence, off to a small diesel shop with some young diesel mechs./computer wizards and on with the tuner. I'm not "rolling smoke" but it is for sure louder, and a little bit smokey when its cold, but hell, its just a hoot to drive now. View attachment 113452View attachment 113453
