    So, what is your axle gear ratio atv_idiot?

    My 780 came to me with 3.42, seems like a good balance, and keeps the revs right around the sweet spot when doing 60-65 mph.

    My truck has 3:55's and I'm at my sweet spot at 1500rpm/68mph. As soon as I hit 1600/70mph my mileage starts dropping and the dash starts telling me to let off the throttle. 
    I found out my truck was spec'd for pulling heavy loads in western Canada through the mountains

    Yep - spend on stacked tuners, each promising hp increase and better fuel economy, until you are at about 2000 hp. That’s where all the increased fuel economy should have you not needing to stop and remove fuel to prevent a spill if driving with a tailwind.

    Funny thing.. My truck has more HP and TQ than I will ever need (D16) Its my gearing that's the issue. Since I am still running both axles and they are lockers, it would take a VERY long time to recoup the cost of gearing change in fuel mileage. Majority of the time its my right foot that needs to be retrained :P

    The nut behind the wheel is responsible for about 80% of the fuel economy.

    Do you know how to adjust that nut for better mileage? I think mine was over tightened :P

  4. Picked up the truck today. Fast start, more power, better response. I was not sure what to expect as I was sure it was a fuel pressure problem. Had to eat some crow!!! Now if it only remains this good?

     

    Tech tool, $140

    Sensor $ 47

    Install $420

    Supplies? $ 67

     

    I'm still happy!!! I have been fighting this the last 5 months, (slow start, poor mileage, slower response of power) I guess I didn't get bad fuel after all.

    Now maybe my MPG will go all the way back up to 6.7. Dick T

    Do you have any info you can share for that 140$ tech tool? Is that for pulling codes? Anyone on the street can purchase??

    Thanks
