Speedo calibration

I have an 05 Excursion w/ Edge Juice w/ Attitude. I run 37's in summer, and 35's in winter. I really need to calibrate my tires to the speedo, and my early release Edge programmer won't do it. Is there a cheap and easy way to correct this?

You can get your speedo calibrated for up to a 35" tire at your dealer but anything bigger you have to get a truspeed

or you can get rid of the edge before it smokes your tranny and buy an SCT that not only will be easier on your trans but you can adjust for tire size too.

SCT will not adjust the speedo. It will work only on the tranny shifts when using the adjusted tire size.

Yes, the SCT xcal2 will recalibrate the ecm for different tire sizes and it will up the trans pressure for firmer shifts and is user adjustable for shift points and other perameters.
