Someone please define ported throttle body "improved throttle response"
What exactly is meant by that? Is it the result of moving throttle tip-in down a little earlier so it feels you have more power sooner in the throttle opening? That would appear to be a more responsive throttle. However, that would probably mean decreased throttle response later in the throttle opening, as the whole band was just moved down. This, of course, is assuming power addition by the inatallation of a ported throttle body is minimal. Any experiences, thoughts, physics, opinions, etc., more than welcome.
I'm attempting to come to a decision on whether, or not, to install a ported throttle body when I have a converter and gears installed this winter. I already have mild cam/heads, LS6 intake manifold, LS6 injectors, longtubes w/highflow cats, X-pipe, GHLs, Blackwing, etc., installed. The car has been LS1 edit dynotuned. Thanks!

I think the improved throttle response is 90% subjective. Somebody said that once now we all want to notice it. Does not seem to be quantifiable.
Having said that, I like my Shaner. Just not sure why.

Idle stability problems arise when the porter gets too creative, especially in the blade closing area. The nastiest ported TB's to deal with are those that have been "ported" behind, on the manifold side of the TB.

90% placebo effect to justify the $ you just wasted....I have put four different intakes on mine and my home-made, radically cut lid with K&N out performs them all.May keep the last one on for the pretty effect even though my car is .1-.2 seconds slower.

Amen!
This is a point I was trying to clarify on a previous post..
