Is it normal for the lc-1 display to fluctuae a lot. For example, while at idle it ranges from 13.9 to 15...constantly jumping between numbers. Also, when i lift between gears the A/F shoots to about 20 for a milisecond.

You are seeing the swing of normal closed loop operation. The 20/lean you see at decel (and gear change if M6) is the operation of decel fuel fuel cutoff and clutch fuel cutoff.

when you got wot it should stay pretty consistent. It most likely won't stay at one afr the whole run but it shouldn't be bouncing around too much.
