I just put 295 tires on and the speedo is slow five mph. Dealer said the computer is flashed for the largest tires it can be. Can anyone tell me where to get one of the correction boxes? Thanks in advance. Larry

I have one, at the recommendation of Stakeman, and am very happy with it.

What he said. Very happy with mine.

 

Yes, very happy with mine.<br><br>A plus is you can dial in 2 sizes of tires,<br>great if you change from summer to winter tires, <br>or huge daily drivers to little drag racing ones ;D .<br><br><br>phox
