Re: Speedo calibration
The speedometer only involves the cluster and not the ECM, which is what the PCV connects to. Any speed correction involves hacking the cluster, which has never been done, or altering the signal from the sensor to the cluster, which is what the SpeedoHealer & SpeedoDRD do.
P.S. If you're worried about the electrical draw, switch your low beam to HID (35 W). That will save 20 W that you can use to power the cell phone or whatever.
