Carbs V Boddies

[77racing]

I am switching my Rover Car over from carbs to Throttle Bodies this year to mainly get my car on the pace for "B" and so I am able to hang onto Graham's shirt sleeves. Part of my preparation will be fuel runs. What do the knowledgeable people think the consumption differences will be?
