high compression boost is flaky even for the professionals. atmospheric conditions can make or break your setup quickly as the tuning curve is small to nil. your engine management setup better be bulletproof.

the only real world advantage to high static comp boost is the increased exhaust gas velocities to better spool larger turbines for quicker boost pickup. but in reality, this only becomes a factor when the turbine is improperly sized or overly large for higher hp applications.
