Calibrate Speedo for 35's

I want to make my speedometer read correctly with my new 35's on my 2012. Also, I assume if I get it to read correctly the on board average gas mileage computer would be more accurate.
I asked a Tech about it
and he said something to the effect that the reprogrammer for the computer was not available yet.
I am not sure if you re gear it or reprogram it.

Any input appreciated.

Thanks!

AEV's Procal $150

There is no Tuner available for the 11-12. That is what he meant.

Yup right now that is about your only option. Not much out for the 2012's. We can do the AEV ProCal for $149.99 shipped and is about our only option...

Bought the AEV ProCal. Took about 2 minutes to make the change. Expensive 2 minutes! If you are going to use one of these. Read the directions. Get your level and tape measure. Speedo is very accurate after the update according to my GPS.

Anyone in the Dallas area that needs to use on. PM me and will see if we can get together.

I live in the DFW area, but there is only one problem. You can only use it on 1 unit at a time. To use it on another Jeep you have to reset the 1st one to factory spec's. I got mine on Friday...
