What’s everyone’s opinions on the mm3 tuner? This is my first Cummins (14 2500 68RFE) and I know a lot of people run efi live. Is this a close match to efi live or better? I just want something reliable and I know a lot of people use efi live and have good luck with it. Was looking into getting the Double R Diesel mm3 tuner with all the tunes
