I have an 06 TJ with 33s still on the 3.07s and when I do get to regear (4.56), I was wondering about the speedometer 36 teeth gear VS. a Speedometer Calibrator/Sensor from 4WheelParts.

Is digital worth the extra money?

Pro/Con?

If the tax man allows it, should the Power Pro Performance Tuner be on my wish list instead of the Edge Trailjammer?

Thanks in advance
