So I have 33" street tires on my Ram and now has 4.56 gears. Being an 01 it doesn't have a speedo gear in the transfer case, it takes a reading from the tone ring on the carrier. My speedo is reading 5mph slower than its actual speed. How do I go about fixing it? Can the SCT 3200 X3 change speedo reading?
