lower intake

[predator5100]

I've asked and no one has answered will i see any signifigant gains if i port and excrude hone the upper and lower intakes as well as throotle body, if i've already port and polished the heads, if so how much. Also this won;t throw my computer off will it.

if your heads are already ported, you need to port the intake because you dont want the intake choking off the heads do you??? but dont get it too big, the BIGGEST the intake should be is as large as the intake port on the heads....

you won't see much if any gains unless you do a cam with it. I also don't think it'll throw your computer off.
