Anyone do any tuning on their LML?
I just loaded an EFI Live from Draconian Diesel. Econo tune gives around 22-21 mpg at 65 mph and 19 mpg at an average of 70-80 mph.
Tow tune with 50 hp gain (not dyno tested on my truck) gives around 20.5 mpg at 65 and 18.5 mpg at 70-80 mph.
best ever miles before tune was 19 mpg at 65 mph.

2012 LML with 119K miles. stock tires and wheels, crew cab, 4x4, long bed.
used for towing hay and tractors, plus travel.
