Default Need advice for P&P throttle body

hey guys,
Im hoping someone can help me out on this one, Ive gotten ahold of another throttle body and wanted to get some advice on how to port and polish it. Meaning whats the best way to do it to get the best overall performance gain from it. The biggest question I have with this is in regards to near the throttle blade. Any advice or info would be great.

I just did this last weekend. http://www.bonnevilleclub.com/forum/...57e1ec207ce632

That thread should help a bit. I got my knowledge from willwren on this as he'* done this a few times. I didn't remove much material as you can see, but it made a difference. Cleaning ALONE helps a lot. You want to round out the sharper edges around the MAF support and polish the walls. You get more gains from porting than you do polishing though so spend more time rounding the sharp edges.

I have three topics posted that clearly detail how to shave the throttle shaft and countersink the screws.

Do NOT remove the MAF support.

You will need a Mill to do it. But the mild cleanup and polishing can be done with a dremel.
