My friend is trying to tell me that Bully Dog is the only tuner that will recal for 37" tires. Please let me know there is more and whick ones. There is case of beer on this!

Thanks, Jason

I have the Hypertech and it recalibrates 37 inch tires. However you have to physically measure your tire with a tape measure. I believe a 37 inch tire, is really a 35 inch tire. (Diameter)
