I had read on here about the Bully Dog products putting too much pressure in the fuel rail. I've got money coming back from taxes and want to get a DD clutch, programmer, maybe the TS-8, airdog or fass fuel filter/pump AND the BADP code free dpf delete. Not totally sure which programmer to go with. I've heard mixed reviews on most all of them. Lots of people happy with their Edge it seems. I'd like to think/hope that Bully Dog might come out with an "off -road" program like Crazy Larry or something. I also would like to wait on the Smarty but who knows when that will come out. Any negatives on the PMT? Thanks for the input!
