I've recently purchased my latest Ram 2500 that was a fresh trade in. It's a 2015 that has been EGR&DPF deleted but previous owner kept the tuner. It had a Smarty MM3 tuner on it. It still has the EGT probe and wiring under the hood. My question is: can I purchase a new MM3 tuner and install it without any issues? The truck runs great with no problems. Previous owner told dealership it has a 30hp tune in it now. Any advise on what I can do or if I can just purchase a new tuner with new tunes will be greatly appreciated?
