I bought an xrt pro race tuner this weekend but gotta wait for funds to get the exhaust.the box says its a street tuner. The place I got it from entered some unlock code so it would work on my 2013.when I tuned it to make sure it recognized my'13 it asked if emissions stuff was on. If I would have checked no is that where I can disable egr and turn off dpf?? Do the street tuners even ask if emmisions are intact?? How do I know its dpf egr delete capable for sure. I purchased one from same guy before but that was before the crackdown:shrug:
