Installed ported T.B. WOW
This must be what my setup needed! Bought a CNC machined T.B. from Katech & did a Coolant bypass while I was at it. The idle lope has become louder same while driving. Midrange power really pulls even more. As the computer adjusts itself I expect even more from this setup. I feel the $165. was well spent

Great that it worked out for you. I was planning on going with a Shaner. What was it about the Katech that made you decide to go with them?
BTW, I've decided to have a Yank SS3200 installed and run it with my 3.15s. Thanks for your thoughts and advice. Another question, did you order the Yank driveplate for $159, or use your stock plate? did you experience any vibration following the torque converter installation?

Katech Ported TB
I was on their site but couldn't find anything about their ported TB. Do you need to call them up about getting one done? Did they do yours or was it on an exchange basis? I may be in the area soon and would like to pick one up.

Call up the Katech website and hold your cursor on "Street Performance" and then click on "Engine Products" when it comes up. Scroll down to "Throttle Bodies" and click on it. Voila!

Throttle Bodies
I have read so much about throttle bodies on the Forum that I am really confused.Some say its a waste of money and some guys say they got real great results from this mod.I wish I knew some one in the area that would allow me to borrow an extra thats been modded so I can get the real scoop.I am not saying these guys are fibbing,but there is an never ending debate on T.B.'s.I would like to try one just to satisfy my curiosity.Question: Do you need to reprogram my computer with this mod or will the computer automatically compensate for the additional air?

The ported ones are 78mm standard GM TB's.
The compuer will "learn" this change in about 100 miles. I'm told no need for a retune, per Shawn & Kirk.
Katech claims 5-6 hp on a stock engine ...........
