There's a guy in Mesa with a dyno, kind of pricey though. ECS Dyno used to have great rates but they seem to closed up shop.
My mileage dropped from a bit over 40 to the mid 30's but, mine's an R3T so tunes are different. I'm not aware of anyone with any Tuneboy experience locally. If you get a dyno run, and the bike is running too rich, you could send the dyno sheet to Wayne and he will tweak the tune for you. Or you could take Pig9R up on his offer and get it exactly right.
