regeared my X from 3.21's to 4.10's. Actually feels like a Jeep now. Checking the speedo vs Garmin GPS shows the speedo to be correct. How can this be? The shop that did the work did NOT recalibrate the speedo. What am I not understanding?
That has to be it.. maybe it reads from something like the abs ring or ?? what I don't know.. but that's cool that it does I guess.. we've got 40 mph winds here today and the Jeep will buck it in 6th ... didn't happen with 3.21's. Mileage change coming I'm sure..
