Yes! He tuned my bike and a couple of my friends bikes last summer. Matt is extremely well at what he does and I wouldn't recommend anyone else.
First time I've had anything tuned where the air to fuel ratio line was almost completely flat across the board (use to get alot of Subarus tuned for about 10 years and its not an easy thing to accomplish).
I have a 2009 zx6r with a power commander 5. Not sure if he deals with Bazzaz or not, but definitely call and ask. If you don't have a Power commander he will discount your tune if you purchase it through him.
Alot of people that tune these days have done thousands of bikes and throw a baseline map on, do a couple tweaks, take your money, and not give a crap. Matt takes his time, lets your ride your bike after the tune and if your not satisfied he will throw it back on and make sure you are.
I believe he has a shop now also and isn't just mobile like he was last summer.
