The mechanics are pretty much the same through all them years. The updated chains came out in the 2011 model year. There was a slight drop in horsepower from 2007 to 2008, but I'm not sure why? May different cam profile or different software programming; I guess one could look up the cam part numbers and check if they were that interested? My 2008 SE gets a little better gas mileage than my 2006 LE. In 2008, they started using NGK OE Iridium spark plugs instead of the NGK Laser platinums, but they are interchangeable.
