    The ALS stands for Anti Lag System.
    That it does is keeps the turbo building boost or on boost by recirculating air from the hot side of the intercooler back into the exhaust while retarding the ignition which creates a better scavenging effect within the engine. This causes the turbo to stay on boost.

    The boost check is done to make sure the launch control strategies are working and to check the turbo speed to make sure the entire system is working correctly.
