Hey guys, I just installed my ported throttle body from Supermod. The throttle response is phenomenal! Anyway, I had a question. If simply porting/widening the throttle body creates such a positive result, such as claims regarding increased hp, and fuel economy, why don't auto companies just make them like that to begin with? I assume that the engineers are highly skilled and know what they are doing, so it a cost saving issue? I would figure the process of making a wider throttle body in the first place would cost the same. Or is it some kind of government regulation? Thanks!
