Your dealership can calibrate for 32's. If they will do it for free, let them. If they charge, get a ProCal. Lots of great features and functions, so it is worth the price.

when i go offroading i stall a bit even in 4lo... im wondering if it's caused by having bigger tires (loss of power) i know my 3.21 gears probably dont help..
would procal fix this? or is it mostly for the speedo?
