Put a new fuel filter in and managed at 25.2 with just over 600 miles on the tank....![]()
It would have to be 125.2 for me to even consider a stinky noisy diesel.

Only 50,000 miles and the BB will have paid for itself in fuel mileage.UPDATE. This has settled in at around 17.6 MPG. I'm frikkin thrilled! Better performance AND better gas mileage. WIN!So far the DIC indicates about 18.2 mpg since the BB tune (about 300 miles). It was 16.2 before I swapped modules. I'll keep you posted.![]()
So are you starting to believe that a tuned, RCSB truck with AFM can get some really good gas mileage?UPDATE. This has settled in at around 17.6 MPG. I'm frikkin thrilled!
