I know this is a stupid stupid stupid question buts I gots ta know
If ya put a 17 on the front the RPM increase. Now if you have not recalibrated the speedo (no Yellow Box connected) does the speedo increase or decrease from the actual. So if I'm doing 100 actual would the speedo indicate lower or higher
Have just put on a 17 at the front 8) 8) what fun. Just waiting delivery of the Yellow Box.
