    Afr readings

    Afr readings today after a little boost. After her being all ran in. At 11 psi
    I have a webber twin choke. One of the tts ones

    On idle 11.7
    Cruising 14.6
    Wide open throttle on 4th 13.7

    Any ideas?

    Only your idol seems a little rich.

    Your WOT is fine for only 11psi. If you are running bigger power then you really need to be in the 12's.

    Normal AFR is 14.7 so when cruising you are more or less perfect. However some people might not agree with this and may think that you need to be a little richer. I would be happy with this though.

    I'd personally say that's abit lean for on boost even at 11psi, I would want to bring it down to at least 13 at a max

    I know those TTS twin carbs are abit fiddly jetting as they have no enrichment circuit for on boost like the 32DIS
