Not that this is all that important but some may consider chip upgrade to get a few more hp and remove the speed limiter. From the speed limiter side I got a little carried away coming back from Minneapolis today and going into a brisk headwind car topped out at 163 mph with a few rpms to go so probably would do 165-170mph with less wind limitation. Seemed to handle nicely around a mild or modest curve or two at these speeds. Noticeable wind howling over sunroof above 120mph or so. Pulled up to these speeds with relative ease and smoothly. Won't be doing it again for awhile out of fear of the law and, well, my wife was none too happy with me either. So at least on my car there seems to be no speed limiter at all.
