  Anyone know a good place to buy a CTI Tuner for a 6.7L Cummins? Last week, I was towing my trailer up a hill, and my truck felt underpowered. A guy at the campsite said a CTI Tuner gave his Ram a serious boost. I'm ready to upgrade mine but don't know where to look. Suggestions?

  I felt the same way towing my camper last summer-my 2019 Cummins was sluggish until I got a CTI Tuner. It really woke the engine up, especially for heavy loads. I found mine through Diesel Performance, and it came with everything needed for a smooth install. Took me about 45 minutes to set up using my old laptop. Just double-check your truck's ECM compatibility first. Been loving the extra power and better fuel mileage since.

  Came across this thread while researching tuners for my 2022 6.7L Cummins. I've been hauling equipment for work, and the stock setup struggles on long grades. A buddy mentioned CTI Tuners for better torque, but I'm still figuring out where to start. Does anyone know if these tuners come with preloaded maps, or do you have to customize everything yourself? Also, curious if anyone's tried a tuner with a bigger intercooler to keep temps down under load. Any experiences out there?
