Can't find "how to bore tb" tech article
 

I used to have a good one bookmarked, but now I cannot find it. I have searched through all the "how to" sites I can think of, but none of them list the throttle body bore article. Could someone please point me to a good article?

Also out of all the people that have done this mod (or bought one), is it worth it? How much gain did it add? I'm all for the every little bit counts school of thought, but if it's only 2-3 hp, I don't think it is worth the chance of me f'ing up a good tb.

Here's one:

There's another one on the jMx page, but I can't seem to locate it at the moment. I think it was under a somewhat unrelated title. Maybe he will jump in here . . .
I think it will yield 6 to 8 hp. If your engine already has heads, cam and headers, obviously you will see a bigger gain. But since it's a free mod, why not? You won't mess it up if you don't get in a big rush, just read the how-to's and take your time.

OK here it is, jmx had it under "infopics"

Thanks Cal, that first one was the one I was looking for.
