I am regretting not getting the 3.73 gear package and want to get 3.73s installed in my 2010, but I don't really want to spring the cost of a tuner just to reset the speedo for the gears. It seems that since you can get a 2010 stock with 3.73s they ought to be able to reflash the ECU for these and keep everything else the same. I called two dealers about this. The first one said they could do 3.55s and that was as close as they could get. The second said changing gears would void my warranty and they wouldn't do a reflash for me anyways. Anyone have any idea...
