    The gear ratio and the tire size affect the speed sensor pulses per mile. Did you change gear ratio or tire size? Are you using a different pcm? If not then you probably don't need to change these...

    It is important to use the correct scale for the 2 BAR MAP. The voltage <> pressure map does not correspond to a 50% split at low range. OEM 2 BAR calibrations sometimes have a wider range between...
