[urq] speaking of 28psi

It is the possible misfires that concern me.
Are they inevitable on the 3B with that much boost?
I haven't brought it to red line since I fixed the wastegate spring.
I think Brandon is running 24psi.
I've considered the c-o-p solution as well.
I have an AAN ECU and wiring harness, but I really didn't want to have
to get into that so soon.
I've spent so much time on this project, I just want to drive it for a
while before I take it down again.
Of course, I don't want to blow it up in the mean time.
