I think it would definately be better than stock, and the accuracy would be off by so little you'd probably not notice, but technically, it won't make it perfect.
This is why...that statement

It still uses a ratio. The further out you go, or faster rather, the more that ratio is off. But again, its better than stock, so the difference You and I would probably never notice as far as accuracy.

GM states the govenor is at 115 MPH.
Your speedometer may say you are going faster than 115, but that doesn't mean you are going faster than 115. The ratio and accuracy of the stock speedometer is probably just off.
I remember it was in a Car&Driver issue - April 2002, here is the link I found and a quote.

In the U.S., manufacturers voluntarily follow the standard set by the Society of Automotive Engineers, J1226, which is pretty lax. To begin with, manufacturers are afforded the latitude to aim for within plus-or-minus two percent of absolute accuracy or to introduce bias to read high on a sliding scale of from minus-one to plus-three percent at low speeds to zero to plus-four percent above 55 mph. And those percentages are not of actual speed but rather a percentage of the total speed range indicated on the dial. So the four-percent allowable range on an 85-mph speedometer is 3.4 mph, and the acceptable range on a 150-mph speedometer is 6.0 mph.<hr></blockquote>
