Best Duramax programmer for mileage

[jeeptj99]

I'm not looking for a race truck.

Doesnt have to be. It's all in how the tuner writes the tune. Now I know how you Chevy homos like your lope tunes but please dont be that person....

Haley, what kind of mileage you getting? Does it get rid of def?
Mine is stock and got around 11.5 towing fifth wheel to the beach. Running 70mph.

I no longer have either due to blown heads and a wreck on the other.
Real world numbers if driven 70 on interstate with cruise I could do around 20-21. Towing I was around 10-12 mo matter how I drove it.
It is hand written tunes and if you only want one tune they can do you just an economy tune instead of the 5 tunes most go with on efi live.
I always dealt with Idaho Rob but there are several that can do efi live like you want.
