    Some of the tuners give you this capability.

    What is the speed rating for the tires you have? Have you done any upgrades to the truck besides putting big rims on it?

    Since your truck is pre 1996 (OBDII) there maybe some tuners that will do it, most tuners need OBDII to work, a chip upgrade might make it possible.

    Tires are the easy part, I think my 265/70R16 Michelin LTX M/S[SUP]2'[/SUP]s are rated up to the 120mph range, my computer cuts off at 99 mph, but my tuner got rid of the limit. I have recorded up to 111.8 with my diagnostic software (speedometer stops at 100 in my truck) at a track.

    First off, I woud not attempt to get the truck to 98MPH again until you have a tire rated for that speed. You stated that your tires are only rated for 80mph! Exceeding that is just plain ignorant. I would not want to be driving my family anywhere near your tragic accident waiting to happen. You are risking your life, any of your passenger's lives, and anyone driving near you lives when you exceed the speed rating of your tires by any amount. After you get some tires rated for higher speeds, then checkout some of these: http://www.autopartswarehouse.com/search/?Ntt=Performance Chip. I am sorry if I seem like a pissed off a$$. I hate to see people blatantly risk the life of innoccent people. .
