Kludges introduce a lot of other problems with the ECM and the VSS is a key input. "Haywire fixes" are from the 80s and belong on the "farm" when we didn't know what the ECM/eproms actually did. Now we do.

Do it right, remove the speed limiter in the eprom. If you get the eprom burning equipment and spend a little time with it you'll get even better performance and better gas mileage that while more than offset the cost.

If you want to make a "short-term cheap decision" (which will cost you in the long run) just contact a custom eprom burner like Ed Wright to remove the speed limiter. Some of the "off-the-shelf" may also remove the speed limiter.
