    sorry to tell you ,but as far as i know you'll never gona get mpg with ten speed like with i-shift ,or even 13 , I hated 10 in one of my trucks so much that i replaced with 13 soon after i got the truck , but mine was used , i see 10 as bad choice , very .

    what do you think the normal gear ratio difference is between a 10 and 13?

    not really important to me since I am sold on the ishift .... just curious

    got the truck 14 days ago and put on 7750 miles and have a 7.2 average.
    pulled milwaukee to seattle with 72,000 pounds and got 6.7 with a big head wind.
    pulled seattle to boston with 76,000 pounds and the best tail wind ever(lasted like 1600 miles), speeds between 62-67 most of the way, 70-75 at times but really kept the speed down and got 7.4 on that trip!
    shifting freakin sucks! but happy with the numbers so far

    I have a 2009 Volvo 780 D13 I shift and I can average 7.65 to 8 easy with mixed heavy and light loads. I also only drive 60-62 mph that makes a huge difference in mpg. On the subject though I was on Volvos website last night and saw the new video for the XE series setup. It's a D13 with I-shift cannot remember the rear gearing. but this things won't even go into 12th gear until 62 mph it also runs 1150 rpm at 65 mph. I really want to know what the fuel mileage is as I am getting ready to order a new truck.

    Gearing ?
    Your cruise rpm? Hp setting , cruise speed, idle time, etc ... That's really low

    Friend is in a 2013 set up to pull flats, and he is way short mileage wise of what the xe spec ones get.

    Not sure if it's a lemon other than downtime, but they have been unable to remedy the situation.

    Not a Volvo aficionado, myself, but I can understand why some work well and others, not so much. His is cruising a couple hundred rpms higher at any given speed than the xe cousins do. And other things which reprogramming the drivetrain hasn't remedied.

    What engine and hp?
    What trans?
    What's his cruise rpm & cruise mph ... It can be sorted out just need to know if it's a spec issue or other....... There are some real stupid Volvo dealers out there that really screw up the specs on stock units for the dealer lots.

    Remember, the D13 is a much lower rpm powerband motor than a Detroit or Cummins.

    If you're cruising over 1400rpm , you're wasting fuel..... Generally 1050-1350 is where you want to stay within cruising for best mpg.
