When will you have the 2010 Ready? Also do these help Gas mileage? Price?
Tuners are performance enhancers first and foremost. I wouldn't buy a tuner with a mind towards mpg improvement. You might see it, then again you might not. If you do...great, if not... don't sweat it because you got it for performance gains. There are just way too many variables involved here.
Bottomline is that there is potential for improvement, but I wouldn't have that as a major contributing reason for getting one. Training your right foot would be far better and cheaper way to improve mpg(although not as fun).
