Here is a very nice review by Mellon Tuning about his experience with this turbo.

This thing makes me want to forgo my plans for OEM turbo power and go big....it makes me crazy!
Look at the torque curve some of these guys are seeing, leveling off at ~4300rpms, that is just insane! People are actually swapping out BB T67's and seeing modest power and insane torque gains!
