So do boosted car need to be SAE corrected???

Or no???

I am confused about this.. and many other things, but this will do for now

u dont sae correct boosted cars cause it dont matter what elevation ur in because it will still run same number no matter where ever you are unlike na cars

Um you are wrong about that, yes you don't use the same correction factor that N/a cars use but boosted cars still loose power the higher the elevation you go up, I would like to see you put down the same #'s up at 5800 ft. compared to sea level, I would put money that you would loose hp, its about half the correction of N/a cars. And if what you are saying is true than how is that many people that have run at bandimere(5800 ft) with turbos consistantly see about a half second difference from when they run at sea level.

TURBO cars at altitude should not use SAE corrected numbers because turbo cars are much less affected by altitude than NA cars. Using SAE correction at altitude on a turbo car will give you some ridiculously inflated dyno numbers. There is a modified version of the SAE correction formula for turbo cars. I'm not sure if this applies to superchraged cars also, however.
