My uncle is wanting a tuner for his 2011 6.7 dodge cummins I told him that the smarty was the way to go. Now my question is he isnt really looking for big horsepower gains just wants better fuel economy should he go with the jr or the sr? What is the difference between the two?

 

the jr is about half power. it is a very good tuner for guys not wanting big power.

 

SR Power


SW # 0 : Half power
SW # 1 : 30 hp increase, with added timing
SW # 2 : 60 hp increase, no added timing ***
SW # 3 : 60 hp increase, with added timing
SW # 4 : 90 hp increase, no added timing ***
SW # 5 : 90 hp increase, with added timing
SW # 6 : 130 hp increase, no added timing ***
SW # 7 : 130 hp increase, with added timing
SW # 8 : 170 hp increase, no added timing *** °°°
SW # 9 : 170 hp increase, with added timing °°°


JR Power
SW # 1 : 40 hp increase
SW # 2 : 70 hp increase
SW # 3 : 100 hp increase

IMO I prefer the Mini Maxx for the 4th gens though, you have guages tune on the fly and the ability to really dial in the economy with MCC plus overdrave trans software.

 

How much is the jr going to be. And how much for the mini maxx
