The whole point here is, the stock ignition curve is too aggressive for increased boost. Ask BMW why they dropped the targeted curve 4 degrees across the board on the 335is in "overboost" mode.
It is nice that the stock ignition curve is set so aggressively from the factory though in that there are gains to be realized with meth and/or race gas on increased boost without altering the ignition tables directly (JB, for example).
