Was curious what the best tune for my 2006 Dodge Cummins 5.9L Turbo Diesel is. I have stacks with a cold air intake and a power puck to stack with...i just didnt know if there were custom tunes on here that would be better than the stacker tunes that come with the predator tuner. Please help a ...

I have an 06 5.9 that also has a idle issue....mine idles right under 1000rpm....i thought one of the features of this programmer was that you could adjust the idle?... anyone out there know how to make my truck idle smoother and at about 1200 rpms?
