I don't mean to sound like anyoneÆs "father" or "family mechanic"; however, disconnecting the speed sensor on a computer controlled vehicle is a very bad thing to do. The speed signal is an intricate part of the equation the computer uses to decide on the final fuel trim. With out it the computer will become confused every time you change the throttle setting and cause very poor drivability. Also it amazes me that any speed demon would buy a Tacoma; it's not built for speed and therefore, it will not do anything "fast" very well. I'm not against a little speed thrill now and then if practiced safely; but I practice that on a motorcycle that is built for a little speed.
