Not to nitpick too much but I will take exception to this. Let me reword...
Even with "proper" SC hardware, software and testing you will have reduced safety margins in any engine.
It all comes down to longevity. More power produces more stress on a variety of components not just engine internals. The lifetime of a stock M3 engine can be very long but supercharging will, statistically speaking, shorten the engines lifetime, both for the failure of internals and other components.
There is no practical way for any small FI company to duplicate (or even get close) to factory endurance and stress testing.
All the being said, AA does have a wonderful reputation and if I even went FI I would go with you guys and a SC kit.
