Edelbrock carb help

my Carter factory books say that the spring on acc pump is tuned. so that under mid peddle pressure it gives the most amount of fuel. and under hard pressure not as much. cause under hard pressure the vacuum jumps fast enough so not as much fuel is needed. but all is this based, IMHO, on stock engine stock carb tuned by the car maker. IMHO, for street driving , mild engine keep things close to stock. just my idea.
