I recently had a re-tune for my 2008 WRX gh.
It's the first time, so I need help in reading the dyno chart.
I'm happy with increase. It feels like driving a totally different car.
I'm not too familiar with how to read the dyno chart, though, especially the chart at the bottom. I think that's the AFR chart? (blue is baseline, red is after tuning).
I just have a 3" bellmouth catless downpipe, HKS legamax premium midpipe and muffler.
Everything else is stock.
Are those numbers good/bad?
TIA for helping a newbie out.
