It may seem to be running fine, but it may not. It's hard to tell without an AFR guage. It can give you a decent indication if you're leaning out or running too rich. A wideband AFR would be key. If you can't afford a wideband, you may want to just go to a dyno and have them measure your afr's while you tune. You may need to find a happy medium between your rrfpr setting and tweeking the afm.

Stoich almost rich? That's your problem. You should not be runninch stoich under load. boosted afr's should be in the region of 12.5:1. You are probly maxing out your injectors if you're using a 10:1 and still cant get rich enough.
