    search for super chip programmers or something. they usually have something to calibrate the speedometer. or you can be cheap like me and buy a garmin with the speed thing built in :D

    They make calibrators that go inline with speedo signal, but I think folks had issues with getting them to work right with the Taco speedo.

    I don't think that the speedo is really adjustable with the stock set up. Depending on your current speedo "error" and the tires you are planning on it may fix your error. You may want to think about re-gearing as well...and I'd talk to a shop about that at least and see what they recommend...

    well its good if you do re-calibrate because your mileage will be off on the odometer. But hey thats good for resell right? lol

    Get a Scangauge II.
    It won't reprogram the computer - but it'll take the information from the computer and change it according to how you have the scangauge setup.
    It'll be just a 'calculated' display so you'll know how fast you're going, etc.

    Do some research ....I know folks use the Scangauge for this purpose.

    I say get a ScangaugeII. You're truck will have lower mileage, and the bonus of having all the functions of the Scangauge....
