New to this. Best Fuel Milage
Hello. I just bought my first diesel truck. 07 Cummins 6.7 Has a mini Maxx installed in it. Been reading up a little on it. Question : What is the setting to get the best fuel mileage? Stock, Tow, Street or Performance?
All trucks respond different to tuning. Your driving also has allot to do with it. What I did was try each power level and check fuel mileage. Left it on the one that provided the best mileage. Typically that's performance.
Ok. Performance is what I have it set on. It used to have big clouds of smoke, then I reset it (mini Maxx) now it won't smoke. Not sure what changed in the settings or hope it was set, but I guess I'm getting better fuel mileage. Changed it from stock to performance and that's what it's been set to. Thank you for the response.
