At an idle with egr off i think its like 45 grams/s. Cruising down the road at 55mph flat and level its like 110grams/s. Full throttle depends on tune. I think mine at full throttle pulls around 400grams/s. Some reference points for you anyways. It should rise very quickly when your getting up to speed. My truck will occasionally 'hang up' where the reading is only half of what it should be and when it does this it has almost no power. Once the reading is correct and the computer sees the correct number it will allow fueling as per the tune table.
