Is this Air fuel ratio correct? What should it be on a healthy 182?

Charlie at Surrey Rolling Road said its running a tad lean? What Could cause that?

Ph1 airbox, caf & performance filter
Rs tuner map

Second graph with torque looks about right to me.

Lambda or ECU temp sensor are worth a look if you're worried, MAP sensor is a possibility.

The figures on the graph a fly hp I assume?

Both lambda sensor and coolant temp sensor are fairly new.
