In my 99 mystique LS (with tach)...will the SVT indiglo Gauges make my speedometer off or not? What I mean by this is will my speed not be accurate. The stock gauges in my vehicle goes up to 130 mph. The SVT indiglo goes up to 160. Can anyone explain in detail if my speedometer will be accurate after I put these in or not, and why?
