I transition from 13.0 @ 0 psi to 11.4 @ 20 psi, with pretty aggressive timing.

I'm trying to get mine in the 11.5-11.8 range but for some reason am having issues, so right now it usually creeps up to 12.5 which is why I don't really let it boost much.

Safety depends on your engine.

Stoich is 12.8 if I am not mistaken. You would be safe at WOT at that level if I am not mistaken. That is my goal atleast.

You're mistaken. Stoich is 14.7:1.

You don't want to run stoich under high levels of boost .. it's too hot.

thats too rich. if you get to much fuel going in, it can dillute/wash the oil off your cylinder walls. try to stay between 10.5 and 12.5(maybe 12 if your at a low altitude)
