The screen costs you at the big end, this is measurable.
Look at your MAP readings with a screened and descreened
piece, if you care to. It's given me no problems, running
an 85mm descreened Delphi truck MAF and a Z06 table.
But people with bent intake tracts can see problems with
fidelity.
How much HP that 459g/sec gives you depends a lot on
motor efficiency and state of tune.
