The superchip allows you to edit the factory tune on the JK. If you have no intentions of doing that, buy the procal. It's easy to use and does an excellent job.

Same thing here. I replaced the stock 32" Rubicon tires with 35x12.5x17 Nitto Trail Grapplers that measured 34" tall mounted with 32 PSI. Took my Garmin and went for a ride.

@ 40 mph speedometer reading my GPS showed I was actually going 43-44 mph.
@ 50 mph speedometer reading my GPS showed I was actually going 56 mph.
@ 60 mph speedometer reading my GPS showed I was actually going 67 mph.

Played with the dip switches on my ProCal and two horn beeps later my speedometer was accurate again.
