I wonder if it can be used in boosted applications.

Per the FAQ:

Can I run boost or Nitrous with the system?
No. The Atomic does not currently have the proper calibration settings to handle any kind of power adders. In an effort to allow for a potential future update, MSD has built in a 2-bar MAP (Manifold Absolute Pressure) Sensor from the factory. If any updates are completed, more information will be released at that time for how a power-adder might be accepted into the Atomic system.
