Hey, anyone know where to grab a CTI Tuner for a 6.7L Cummins? I was hauling some gear last weekend, and my buddy’s tuned Ram just smoked mine on power. He mentioned the CTI Tuner but didn’t say where he got it. I’m dying to boost my truck’s performance for towing. Any tips or spots you guys trust?
I got my CTI Tuner a while back and it’s been a game-changer for my 2022 Ram 6.7L. I was in the same boat, struggling with sluggish throttle response until I found a solid spot to pick one up. Check out Diesel Tuners for the tuner—it’s straightforward and worked great for me. I had a local shop help with the install, and now towing my trailer feels effortless. The remote tuning process was quick, about 30 minutes, and the truck runs smoother with better fuel economy. Just make sure you’ve got a Windows laptop ready for the setup.
I’ve been looking into tuners for my 2023 Cummins too, so this thread caught my eye. Last summer, I was towing my camper up a steep grade, and the stock power just wasn’t cutting it—felt like the engine was begging for more. I haven’t pulled the trigger on a CTI yet, but I’ve heard it’s solid for deleting emissions and boosting power. I’m curious if anyone’s tried pairing it with an aftermarket exhaust to really open things up. My mechanic mentioned it could help with turbo lag, but I’m still researching what’s out there. Anyone got experience with that combo or other tuners for the 6.7L? I’m all ears for real-world stories before I decide what to buy.
