^If you say so, but now it makes alot more sense why I have had several EJ257s come in with blown ring lands and now they are all running between 12.2 and 12.7 AFR at WOT with no issues.

I've heard of ringland's going out on these motors but I didn't know it was caused by running rich. Well, from what I've read here just confirmed what you have said.

12.5-13.3 is deemed safe and that running at 11 being "considered safe" can cause gas to build up on the ringland's and if/when that ignites, will destroy the ringland's.
