On recommendation of CamaroDreams76 and 1JEWELDSSRS, I swapped out throttle body for ported TB! I went with new one from Katech. Great recommendation guys, I am very happy with this mod!
Have only logged about 30 minutes on it. Gave it a chance to relearn... seems to still be figuring out idle speed (sometimes jumps to 1K rpm). Throttle response definitely improved! Notice it in rev matching. And honestly, I would swear there's a bit more there at WOT above 3K rpm. Also a bit more intake noise with more of a "howl" sound? Am I imagining all this, or possible with a ported TB? I do feel power more readily accessible. Bottom line, car is even more fun to drive than it was this morning!
Oh, and only took 10 minutes and got to peek inside intake manifold. Catch can working good!
