I looked in to them called them and they don't work on chargers but there is tune time performance I'm looking in to in Lakewood njI was just looking into this myself and found this website http://www.dynojet.com/dyno_centers/dynocenters1_output.aspx?state=NJ
I am not sure about them but I have seen people really liking Big Daddy Performance in Lakewood, NJ
Yea a lot of places I'm finding don't do chargers cuz the on board computer different. But tune time priced me like 850 with the diablo sport tuner and the custom dyno tune. They use the diablo to get into the on board computerThanks for the heads up! I was not sure if they were only mustang or if they worked on all cars.
