It's intercooler pressure drop. For a scientific explanation scroll halfway down this page to the section titled "Pressure Drop."

RE: boost after FMIC install
When I did my fmic, I didn't lose any boost at all. Just curious, you did use 2.5 inch piping or bigger, right?
Jaxspeeddemon originally had a fmic installed with 2.1inch piping and he lost about 8psi in every gear, from 25 to about 17psi.
