Software. I use the AEV Pro Cal. Sweet wheels.tdm said:Here's a question for you all. On my 05 I had to change the speedo gear when I put the 33's on. I don't know if this new rig has had the speedo adjusted by the dealer...they put the wheels on the day I bought it, came off the delivery truck the day before. I really don't know if it's accurate or not.
Does the 2013 still use speedo gears, or is it an adjustment done in the software by the dealer?
