I’v always had tuners, bolt ons and gizmos on all my cars and trucks and now i just bought this for my 2017 hemi 1500 . I installed 35 in tires . Full body 4 inch lift kit and flowmaster exhaust and kNn intake and this piggy back tuner does everything i expected and so much more ! Econo when i wanna be conservative” (very few times now that i actually love driving my truck lol) Towing when pulling my sleds and trailers and of course the aggressive power band mode . Now that’s where i realized wow so THIS IS WHAT A HEMI IS SUPPOSED TO FEEL LIKE . Guys – Don’t even put it up for debate ! This is by far the best tuner for a hemi out there hands down 10/10 satisfied !
