I was hoping to get some help on the best tuner for my 2018 2500.

I own a construction business and do some towing of trailers and dump trailers.

I’m not interested in burning down the track and I don’t want to risk hurting my Engine but I do want to maximize its performance and power while gaining gas mileage.

Also I want to get rid of all the EPA BS on the exhaust at some point.

Any help?
