The advanced off boost timing idea doesn't really directly effect turbo lag, it just gives better off-boost performance. Because the engine revs up quicker, the turbo will then spin sooner, so indirectly there is less perceived lag. When the boost comes on, you retard back to stock with the shaved stop pin neutralizing the extra basic advance. Or perhaps slightly more retard to reduce knock at full boost. The 2nd generation spg9 AID does the latter.
