    if you are taping the the pedal in either truck, they will sip gas/diesel. If you jam the pedal to the concrete, the mpg's will go down, the percentage will be allot less in the dmax. I will have to find a site that does a side by side comparison of equally upgraded silverado's.

    Either truck at 600hp will not give you 15mpg or 24mpg. The 5.3L might hit 8mpg's @ 600hp...... the diesel might get you 12-15mpg's (24pmg's being the normal bottom end.
    Huh? What's that got to do with you justifying a Dmax with fuel econ that you plan to sabotage by taking it to 600+ HP???

    I'm guessing the way he tuned the truck, geared it, use of the propane injection, as well as the Allison 1000 transmission which is amazing. Remember extra power makes moving alot of weight easier. Say I were to put a Dmax in the Tahoe. Because the Dmax is built for 8,000-13,000lb trucks it will move my 5,400lb truck like it weights nothing which saves gas because the engine doesn't work hard or it doesn't have to work as hard as long. Its all basic physics.

    Btw that extra 1,000lb in rims helps increase the centripetal(Did I use the right word I know what one I want) force of the wheels while going down the highway. Therefore the truck's engine doesn't have to work very hard.

    Enkei, is there anyway you can get a list of the upgrades and links to the upgrades he did to bring his MPG's back up with the extra HP, extra weight he is lugging around (PM me the info), I need to put a list together for the truck that is replacing my current truck so I have a starting point.

    I assume a 2500 being a little lighter with the upgrades he did might keep me on the high end of 22-25mpg/s (which is 7-10 mpg's higher than the truck I am in now).

    I find that hard to believe, but if it's true, could you pm me what you changed to get that? I am looking at an 09-11 dmax and need a list so I can start the ground running to upgrade the HP and the Fuel econ.

    Even if I end up paying a shop to do the upgrades cause I am not going to have the bandwidth in my schedule to get them done myself.
