With the stock maf and suppposed stock boost you should be much richer than .91, thats actually pretty lean. Stock settings are always set pretty rich, im not sure if you Eprom is programmed to change and AF ratios or whatever but it seems your too lean based on the narrowband.... which isnt very accurate.

Throw a cheap boost guage in there and see what its hitting, then maybe put an AFC in there and see if you can richen it up a tad.
