There have been crack downs of late, H+S tuners got taped pretty hard 2-3 years ago, quadzilla, and Sinister diesel. Recently Diablo got popped but that was more for their gas engine tuners.
Small places like HPP, PPEI (who I would recommend to you with with a ‘max, Kory Willis is the man on duramax tuning) they’re harder to go after since they have a huge presence in the racing world also.
Just check the box that says yes I know it’s for ‘off-road and racinguse only’ and move on to a much better running, happier,, longer lasting truck.
