im thinking of getting my throttle body bore, port, and polished . i have a sirII throtle body . its 60mm. stock . it would be 64mm. after the bore, port, and polished !
what type of performance increase should i expect ? is it goin to be noticiable ? i just want to know if its worth the money to go out and get this done . thanks in advance

edit: my mods are : aem intake, comptech header, cat back exhaust, test pipe
skunk2 intake manifold, b&m fuel pressure regulator, aem cam gears, ground kit im running a ITR ecu along with a APEXi VAFC .

It wouldn't be 'Ported and Polished' .... only cylinder heads get that work. You're throttle body will be 'Bored to 64mm and Tapered to 68mm'.

You can only expect as much gains as your other modifications. If you have a stock motor, you will barely feel anything. zIf you already have an intake manifold, GOOD header and maybe some cams... you'll DEFNITELY feel a difference.

I'm doubting it. You also have to consider the fact that different engines with different mods will not always react the same to any additional mods.
