Not to go on beating an overly done good guy post and not to bring up again the issues people have had with MM, I'm just commenting on my experience with him using his tuning services.

While his schedule isn't the most flexible he's awesome to work with and will do what it takes to make sure your car is up and running the way it should! Not only that he's a great resource to ask questions about your car and the calibration process (even stupid questions).

For that I give him my thumbs up and highly recommend him to anyone using a COBB AP and looking for a tuner.

I have the GReddy turbo kit (with fixes) and was tuned prior with the X-intercept. So far MM's calibrations have made the car much smoother and feels faster (butt dyno) while producing slight MPG gains.

 

yep Jeff is easy to work with and resourceful.

+ 1 for MM.
