With self control the bigger the tune the better the mileage.

for sure? That's how it was on my lly. I always ran the 135 and got the best.....but seems maybe the worst on the lmm....or so I've heard the 70 n 90 tunes run the best.........any thoughts or research

Ever Duramax will run differently on the same tune. Some better some worst. Just have to run 4 or 5 tanks and log the type of driving and mpg and then switch to the next level and 4 or 5 tanks on that level. Then compare from there.
