Tune, Delete???
 

I’m looking to tune and delete my 2018 Cummins 2500. I don’t want a race truck. I don’t want lots of black smoke, I don’t want a super loud exhaust. I just want a little more HP to improve drive ability when pulling a boat/camper. My question is what are you guys running? What’s the best tuner? I’m leaning towards EFI. But what should I do with the exhaust? Muffler, no muffler, resonator? Let me know
