700 FI - Fuel Mapping

[koby]

So as per some previous discussion on the subject of re-mapping the fuel injection on the 700, the experience to date has been to increase the fuel from the factory setting of "0" to a maximum of "129".
Riching the mixture to the max has been reported to potential increase horsepower by 16%. I have tried this and "YES there is a noticable difference, but with some adverse effects on idle to 1500 rpm range, (stalling, over fuel sputter).

My question is:

Has anyone gone the other way and leaned it out? I realize the risks involved in detonation, but am thinking of mixing 25% C-111 with premium and giving it a whirl at around the -10 to -20 range and see how it does.

If anybody has tried it, I sure would like to hear the results.
