The drawback with this is that it might start having problems idling.

i already have all those. The ECU it self is programmed in a way that it does not recognize values above 14.7:1 AFR. so if you define a value above 14.7:1 it will just ignore and do what it 'thinks' is best. usually 14.7:1.
in any case, I tihnk 16.7-17:1 is too lean? From books and online resource I see 15.5-16:1 being quote as best figures for economy:
even still i feel no difference in power at 17:1 vs 15:1 stock. throttle feels the same.
