    Wonder what the likelyhood is of your afr setup being correct and his not so much??

    It's possible but I'm going to be conservative and assume his leaner numbers are where I'm really at just to play it safe

    My question is, are you still on the ~425cc TRD injectors? I imagine yes.

    He is probably reading after the cats which if I remember correctly will make things seem more lean.

    It is reading after the cats. He swapped his sensor in place of mine in the rear passenger bung location on the URD ypipe, so the location was the same where my gauge was reading slightly rich

    So 12.5 is considered too lean for these trucks? What is the ideal afr? I really need to hook up my AFR and see what’s going on :)

    11.3 to 11.5 ish I believe is ideal for our superchargers

    I'm also running the infamous Bosch afr sensor that @12TRDTacoma so despises :)

    So my sensor could be off even though it came new with the gauge and has only a couple months use

    Running around 92% injector duty cycle, with the assumption of a ~15% drivetrain loss.

    Needs the FPR mod, as a temp fix(make sure to monitor AFR's), but primarily larger injectors.

    Don't try to make more power, without addressing those. At least if you want to play it safe.
