Dyno Chart - How to Interpret
 
I just had a re-tune for my 2008 WRX gh. Embedded below is the dyno chart.

It's my first time doing this, so I need help in interpreting the chart.

Mods in my car: 3" Bellmouth catless downpipe, HKS Legamax Premium midpipe and muffler. Everything else is stock.

I'm happy with the very noticeable increase in torque. The car feels totally different to drive now. But I need help interpreting the graph at the bottom - is that the AFR chart? Are those good numbers there?

TIA for helping out a newbie.

Looks like it should be the a/f and boost on the bottom chart but with nothing on the side or a chart to show what each color represents its hard to tell

i think the blue line is the baseline, and the red line is after tuning?

I confirmed that that chart is the AFR chart.

So, that means i'm running in the lean (~15) from 2.75k to 3.8k rpms, after which it starts to go rich ~11-12 until redline. Is this good?
