    I have a 1998 K2500 with the 5.7 and 3.73 gears. For me it is geared to low with 3.73 gears. I use it for a daily driver
    and it takes getting it to 50 mph before it fully shifts to overdrive and T/C locked. Is there a tuner that I can use to
    change the shift points or do I need a custom tune to do it. Thanks for the help in advance.

    you need to go to a shop and get a custom tune done... there's no handheld programmers available that support your 1998 truck... you'll need to go to a shop that uses hptuners software....

    look at nelsons performance or blackbear performance they do mail order tunes, there way better than any hand held programmer
