Going from a large tire to a smaller tire will not make your MPG drop, it will increase it some. With going to a smaller tire you have less rotational displacement, thus less force to move.
As far as a tuner gos, I would look into something from DPtuner, they have some really good stuff and from what I am seeing its worth the cost.
Another thing that will make you have better MPG is restrictions. Any time you can open up an engine I.E. intake, exhaust ect... will help with better fuel atomization
Most important of all KEEP YOUR FOOT OUT OF HER lol... below 2k rpm is the best help lol.....
I hope this will help you out some buddy
