One of the pilot stories (show in this thread) before did mention black smoke comming from the exhaust and the plane vibrating a lot. Sound like he was pushing it a bit too far. But none of the others mentioned it.

Prior to the 12lb mod/100 octane, if you pulled the boost override you would get 18lb boost up to about 5000ft, 16 lb boost to about 7500ft, 12 lb boost to about 11000ft and 7lb boost at ~17500ft. 7lb was the maximum permissible with 87 octane so the altitude range that it would be beneficial is very restricted; below that altitude power would be reduced because detonation would occur, engine would no longer run smoothly and the engine would quickly fail altogther. The only way that the boost override would be beneficial would be if it had a mod to restrict the additional boost to ~7lb, but of course this would only result in a very modest power increase, and this mod was never done.

AFAIK, the 109E was limited to 7lb boost as well (1.4 ATA) when using 87 octane.
