I could grab a wideband, but I'm assuming it would do no good in a post cat o2 sensor location?
It will be off by a bit, but not much. Most dynos use tail pipe sniffers and they're pretty accurate.
I wonder if my injectors/fuel filter could be clogged?
Nothing in your log would indicate that... you're open loop so whatever the ECU is requesting isn't going to be affected by that. Bank1 looks a bit lean, but that could be O2 sensor - you can never trust narrow bands.
Or if they are just maxing out.. In that case has anyone run slightly uprated injectors on this tune?
This. They are maxed. You could run bigger injectors, but honestly your log looks pretty good as is, and you can't really run much more boost on k03s.
Btw nyet, thanks so much for ecuxplot
You're VERY welcome! Please feel free to post feedback, bug reports, questions, etc. BTW you might want to grab the latest version, you are using an older version where the colors start repeating (see your knock voltage logs...) Also, the latest version has presets so you can batch export a bunch of graphs at once
