I also offer a similar (and cheaper product) from the company that builds the Interceptors for us called the Recalibrator - $149.00 w/ free shipping.

Excellent for correcting the speedo which then helps the ABS function etter with the taller (or shorter) tires. It has already been installed and tested on a VX - email me for install instructions if interested.
