I have a 2015 ram 2500 mega cab 6.7.
I have a rame me ultra programmer on my truck and i haven't done anything with it since it was installed other that go back and forth using the pre programmed tunes.
I heard there were some software updates that have better tunes in them that have better fuel mileage settings. Does anyone know if this is true and if so how do i change get them and install them. Or where i can get custom tunes for my truck...i would like to get better fuel mileage when I'm not towing anything.
Also what's the difference between street, preformance, and the race tunes... currently i only is the towing and performance tunes.
Thanks
