Several people have criticized bjjranger for posting about a throttle body optimization that already has a how-to procedure on the CEG website and has been discussed for a long time on here. However, I found his post quite informative.

His link provided the only pics I've seen of how to modify the halfshaft and they make it quite clear on what to do. The CEG how-to is difficult to understand in that area and, although many people have complained, no one has edited it.
