I have a 2004 Dodge Ram 2500 4x4 with a 5.9 [high output] diesel engine in it. I am looking for suggestions for the best after market fuel management system. I am looking for more miles per gallon of fuel. I am not after more HP, although if that happens, without damage to engine, I will not be upset. I am going to start pulling a 30' gooseneck trailer loaded with a 50+ hp tractor with front end loader & brush hog on it, from time to time.
Thanks for any help.

That's some weight.

There is the bullydog, and edge programmers that I am aware of.... but, I suspect that any 'economy' settings they may have will actually reduce power output... not exactly what you want when you are pulling the heavy stuff.

 

Definitely better to not do economy settings.
