Howdy,

i just just ordered a 2017 Lairime Longhorn 2500 and the first thing I'm doing is putting a 3" suspension lift and 325/50R22 wheels and tires on it. My question is, what do I have to do to calibrate the computer for the bigger tires? I know pretty much every performance tuner has this calibration included, but is there a way of doing this without buying an engine tuner?

Thanks
