Funny you mention this. Enthalpy and I recently had a long discussion and this came up, iirc he did say that most of the Japanese tunes (JWT, mines, etc...) all contain far too much ignition advance for use here in Florida, at least. We reasoned that it was the availability of 98 octane fuel, and the colder temperatures there in Japan, that allow for such timing numbers.

This car, I tuned on 93 years ago, stock bottom end redtop. Still together after 35,000 miles
more fwiw. I think if you have a good timing map (Ill say it again, about 9* btdc at this boost level for mid-range) It seems to last alot longer. I know exactly what you mean though, about the OEM ringlands, they are certainly a weak point; One small mistake and they are gone. It is not recommended to use the stock piston at this power level due to the narrow margin for error.
