boost is pressure and pressure is a measurement of restriction. with a higher flowing intake you are flowing more CFM. so while you're boost (restriction) will be "less" even though you're still flowing the same amount of air (cfm).
for example, take a supercharged mustang. bone stock engine and the thing pushes 10 pounds and makes say 400hp. put some headers on it, and an open exhaust, throw some ported heads and larger cam. now that same mustang with the same pulleys will probably be making only 7 or 8 pounds of boost yet it's making more power because the engine is running more efficiently and probably making around 500hp......
