Howdy folks need a little help here. What I need to know is can the mm3 do tire size and gear ratio recalibration.
I have a 16 2500 Cummins with 37s and 4.10 gears. Deleted. Unfortunately what I'm using now does not do tire size and gear ratio.
I tried using hyper tech recalibration tool but the delete over rides the recalibration.
So my question is...... Is the mm3 capable of doing so in my truck and is it accurate.
Thanks.
