As for AFR at WOT, I've seen anywhere from 12.5:0-13:0 used on the VHR. Mine is tuned for 13.2:0 at WOT, with pretty much stock ignition timing (i have an HR G sedan)

Thanks for the reply on this A/F Target. Since I posted the question I found that most tune between 12.5 and 13.5, so I would just go for 13.0 and lean out while watching the EGTs. But for non-racers, I'm sure 13.0 is fine.
Do you know what the WOT Ignition Time hits for # of degrees BTDC?
