is this a dumb question I have a lid k and n, 85mm slp maf, ( i didnt buy) and a bbk tb, and a ls6 intake unported, am I bottlenecking my intake? I get a bazar whistle at cold startup, whistles like an AIR system, but my system I took out....always has done it, either way my real question is am I bottlnecking? and is it bad if I am? thanks!

ported stocker is what you want

I already have a ported stock TB but an LS1 intake manifold... I have a BBK intake manifold going on and was going to get a BBK 80mm TB, sound good? (BBK intake is 85mm)

Sorry to Hijack!

Port the stocker to 78 mm and sell the BBK.
