Can a misfire show up as knock?

Can it show up by looking the misfire pids? I didn't feel/hear anything unusual.

If you are logging the O2 voltages you will see it dip down when it misfires.

Makes sense I'll check it out.

I'm running TR6's gapped at 0.028. Should I be looking for other plugs? In the end I'm hoping for 13-15psi with water/meth injection. Maybe BR7EF's are in order?

I would do 7s over 8psi.

yeah go br7s for sure! and if you are spraying a healthy amount of meth you are not too rich yet.

I've been using the same TR6's for about 8k miles now with 10-12psi at Factory pre-gap. Planning on going to 15psi soon so time to upgrade

I'm not spraying any water/meth at the moment with 11.0 AFR (0.778 lambda) and 11 deg of timing.

I just bumped it up to lambda 0.786 and 13 deg of timing and will try it out tomorrow. And I'll get some BR7EF's ordered. What gap would you recommend? 0.028" seems common.
