  1. Dealer Speedometer Recalibration

    Hey all, I've been debating whether to buy a speedo recalibrator (cheapest one I saw was around $140) or have the dealership perform it ($125).

I have the direction indicator set to be in the upper right hand corner of my center speedometer display and...
  8. Here is the cost to adjust speedometer for bigger tires

On the JLU it is a simple software tweak but of course the dealer wants to make that costly. $125 for the "contract" with Chrysler to buy the software. $65...
