AFRs - What should I be looking for?

My peak AFR @ Thor was 14.89 and my lowest 10.7 @ 6800rpm, I guess something needs to be done to sort this out?

 

AFR Dyno Plot

 

Am I right in thinking the eManage should release some more BHP / torque from my black whale?

 

Is there a dummies guide to AFR anywhere? Do I need the on boost reading to be higher than that and if so am I right in thinking that involves less fuel or more air? Would a figure of around 11.5 be the way forward when boosting?

 

I have another pre BPU dyno plot here - it's slightly easier to read the AFR on that one.

yr afr is safe rich under full boost. which is good and normal for stock ecu, but leaner would produce a bit more power. u r already around 11.5 as an average. u'll find extra power around the 12's but its very very risky, the lower u go.
