Does anyone have a real answer? I mean if it losses HP when it is installed then why do people use it or install it or even keep using it?

AEM themselves won't make a negative comment as to it's loss but, I'm curious about the Real answer.

I still see loads of cars witht he origional AEM/CAI and very few witht he valve installed. Of course I'm looking at real track cars but, anyways...

Thanks guys,

A.
