[QUOTE="NEVRNF, post: 1427429, member: 709"] I just bought a 2011. Couple of things I noticed. Speedo was off 3-4 mph with the stock tires. On fill ups the gallons used on the trip display always shows 1.5-3 gallons less than what is actually filled up. The lie o meter is always showing much higher than calculated. Since I added the new shoes 35x12.5x20 Nitto Ridge Grapplers the speedo is now only off by 1. I also have the jerky down shift and it happens mostly on a cold trans and usually only within the 1st minute of driving. it has been on a diet previously so I have no before and after comparison. I am running canned H&S XRT Pro tunes. The only other thing to add to the OP is to purchase the Outlet Pipe upgrade also. The previous owner did this after having it explode while on a road trip with his boat and being stranded. These are my observations after 60 days of ownership. [/QUOTE]
