    Impeller makes no difference on these. Need more power.
    Airbox mod, no point, much better to just fit a cone filter and fab up a small adapter to be able to tee in the PCV.

    So I'm pretty sure it's on at this point - going to pull the engine out just after the end of the season and put it on a dyno here and finetune it, so the holeshot is better as well.

    I mean there is some trim, but not much. I can disassemble the file further and find all the maps. They're probably looked up just before or just after the main ignition maps.

    Yeah, it's there.
    I wonder why it gets stuck at 25-30km/h sometimes randomly though. Was thinking GPS issues.
    Either way, seems quite accurate to me.
