I am new to this site and to the Cummins work. I have a 2013 3500 and was thinking about the Raceme tuner? Are there any issues. I have gone through some threads that seem to have update issues but don’t know if that apples to the box tunes or is that only for the Warp or custom tunes? My last truck had stacked super chip and edge juice box but once installed I never touched it again, especially for updates. I am still trying to catch up to all the new technology and only want to buy a tuner once, that gives me better mpg and I don’t have to sacrifice performance. Am I asking too much? Are the race me any good?
