each engine is different, But those maps are pretty high, you have to see where the car is running on the map on full load, my car runs along P16 on high boost, this depends majorly on how close your airflow meters are to maxing out etc.
high numbers in the timing in low load area's can be tolerated when the car is off boost just as if it's an Naturally aspirated engine(best way to set this is on a dyno and adjust the timing to find the best advance to power gained, hard to explain), but once it starts to ramp onto boost the timing numbers decrease radically, all this needs to be tuned to suit each engine and each setup, using knock detection.
the stock power fc maps have some stupidly high numbers say from P9 to P20, and the more boost you run the more you need to decrease the timing.
even the idle is pretty high, what engine is this map from? before any timing numbers are changed it is EXTREMELY important to make sure what the ecu is reading corresponds to what a timing light is reading on the crank, so the ecu and engine are in sync
