Hello everyone, quick question (I am sure there is a thread somewhere about this already just can't find it) I have recently just got got a 2014 6.7 and was curious what tuner would be best ? Looking for a monitor not just a plug an tune. I also live in the great state of Massachusetts so the emissions laws blow up so it would be nice if the tuner did *** and egr ******s. I understand the tuner won't help pass inspection, but no one likes engine lights Thanks for the help guys !!
