Hey, i went out tonight with the intention of seeing what my current modifications would do to affect my top speed. To my surprise my car burried the speedometer at 150mph! I know that this is not the actual speed i was going and was wondering if any one knows the approximate % of accuracy that a teg's speedo has at that speed, my only modifications are 205's on stock rims, H&R race springs, Koni yellow shocks, AEM CAI, edlebrock 65mm TB, skunk 2 intake manifold, and denso iridium spark plugs. I went out expecting speeds of about 140, and to my surprise got to 150 and fairly quickly. If you have any idea of that accuracy % let me know.
