You probably already know this? I have found that if you reset the mileage meter after every refill of fuel, it remains very accurate. If you do not reset it after every fuel stop, it is running an average total of all the miles you have driven from day one. See if this makes it more accurate? My gage usually stays accurate +-.5MPG after re setting.

I do reset my gauge after every fill up, and with my power module off it is accurate to within +-.5MPG as well. I know why it is so far off when my module is on, my question was how many of these posts saying, after a chip or module was put on, that they are getting mileage in the mid-20's is what the mileage computer is saying or it is hand figured by dividing the miles traveled between fill ups and the gallons used.

How to increase power in an older diesel? by pompano

I have a 1999 Dodge Ram Quad cab, 4X4, Laramie 2500 diesel with 246,000 miles on it. Have never done any extras to the engine so far, but now would like to pull a 5th Wheel RV for a couple of seasons before selling the pickup or trading in on a new one. The trailer weighs about 14,000 lbs with all gear, tanks full, etc. What 'chip' or other features can I add to this engine to give me that extra power needed? In addition, can/should I do anything to the transmission/rear end? Thanks for the helpful info.

Cummins compaired to what? tractor truck. I know to many people with 7.3 powerstokes not standing up to much towing. The only thing is i`ve read mercadies is going to stop on cummins 2007 i believe so get one while you can.cummins says it`ll run over 300,000 miles inbetween over haul. I think its the best motor on the market. After all cummins knows how to buildem.

The new Common Rail Cummins has not been out for long enough for me to get a good feel as to how long it will be reliable. The older 12 valve was as reliable as you can get, I have seen them at over 400,000 miles and the engine still runs good. My dad has a 24 valve that has 250,000+ miles on it and still runs good.

You can put on high flow air filters and exhaust, injectors, and turbo modifications. As for a "chip", I prefer power modules that go after the computer than a simple chip that goes in the computer and just increases fuel flow. On the 98.5-02 Cummins Quadzilla will have a $349 XZT towing module that adds 60Hp or $499 adjustable Xzilleraider that adds up 120Hp, these should be out by the start of the new year.

I agree with everything tom250ibs stated! I have also heard the rumors that ALL the diesel truck motors are switching hands. The biggest rumor is that Caterpillar is coming into the ball game with one of the big 3 manufactures trucks. Caterpillar also knows how to build them (if they will build them in the US). My opinion on mileage is this: I would think you could easily get over 300,000 on a Cummins, if you take care of the recomended PM's.
