how far can the stock speedo be recalibrated? how is this done?Originally posted by David Muench
The truspeed won't work, it's been tried. The stock speedo can't be reprogrammed far enough. I don't know of anyone who has managed to recalibrate their speedo with the 315's yet. . If anyone has, please let me know how.
