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?
