I usually aim for 13-13.5 at WOT. But take it to a dyno to find the sweet spot where it makes most power. Then keep adding fuel until it drops a bit and go ack to the previous setting.
If it's going to run at WOT most of the time or for long periods of time you might want to be a little conservative and run it a bit rich so you won't blow the engine.
