I will be picking up a 2020 Freightliner mt55 with a 6.7 in it in early November. Looking at tuning it for better economy. Not looking for DPF stuff, DOT would be an issue so i was wondering what is out there for medium duty stuff emissions intact?

I was looking at the Bully Dog medium duty GT but kinda wanted something else. I've never been a fan of Bully dog but kinda SOL in this area I guess.

Any way, not a Dodge Ram but it is a Cummins so I was wondering what y'all know. Thanks
