As most of you are aware most tacomas cut out at approximately 105 mph. However... if you unplug one of the transmission sensors(on 2000 and newer, older models are connected by a cable) near the rear passenger side of the tranny(manuel transmission, I haven't tried automatic), it'll disable the speedometer and odometer. The downside is... the check engine light comes on and you can't see how fast your going. The upside is... you get to top out your tacoma and keep low miles on it while doing so.
