Hi Paul,

Thank you for your interest in Dynatek ignitions. Yes, some 2006 models do appear to have some speedometer calibration issue with the DSPT-1. Apparently some models have a different final drive ratio that causes this. The main solution we have seen is to use a speedometer calibration device. There are several listed online. If we can be of any future assistance please feel free to contact us anytime.
