Conditioning is only step 1. You have to put it in your fridge for several days to a week. Your producing a lot of CO2, but most of it is stuck in the headspace of the bottle, when you chill the beer at fridge temps it absorbs the CO2 better and it goes into the beer.
3.37oz is also on the low side for a whole 5 gallons, but you should still have some carbonation...chill it for a few days and let us know.
