Well that's a little extreme. OEM tends to leave some room on the table on a lot of engines, but they do so for the sake of reliability and durability. If stock intakes had the best flow, there wouldn't be a reason for the aftermarket. Same for exhaust manifolds vs headers. Granted, most of these "better" units are for the purpose of making more power, but the theory is still that an engine that breathes easier will burn less gas. And diesel programmers are able to make lots more power with computer tuning and nothing else; whether or not that comes at the cost of reliabilty is not something I can comment on.
