Still in one piece, 19xx miles. Pulling 13.5 mpg back and forth to work daily (2 mpg increase !). Still on stock 6.0 tune. Next, 44 lb. inj.'s (suggested by Allen), and one of Allens tunes. Soon to follow the tune will be the new Fuddle HD Truck 'verter. Will have data on highway mpg this weekend.

Took a 250 mile ride since last post. 98% highway. Pulled 16 mpg on way to Mtn. Lk., 3 mpg better than previous best with the 6.0L. On the way back I got mileage. Average of 70 MPH both ways. Seemed as though lockup was not staying in when it should. Allen is working on my 93 octane tune as I post. When correctly tuned for the low RPM beast, all should be cool.
