Think of that differently: Power - Performance. Different term, but similar results. Power is a hard option to obtain. Performance is easy to obtain and will cost you less. Those Add-ons items, that claim to give you Power are not really giving you power, but more so Performance. People who are claiming to have added Power, really don't have it, they got performance instead. Power Creators are Turbos, Superchargers and Engine Modifications. Things like Gear changes, Intake changes, Tuners, Exhaust changes are "Performance" enhancers not Power makers. Some people you see online with these super HP numbers, are just number adders: People that calculate how much power a Intake claims, a Exhaust claims they add it up and say that's how much HP they have, but Only a Gyno can tell you how much your Eng is making.
