P&p throttle body
Yeah, don't port near where the butterfly rests when it's shut...if you do then too much air will bypass the blade and your car will idle too high. Also don't get too greedy sanding down the "hump" or you can break through to the outside of the housing then you're stuck using JB weld to fill the hole. Last thing is if you're doing the bump stop mod then don't allow the blade to open more than 90 degrees or you will trip a TPS error and corresponding check engine light. It's really not a difficult trade to master it just takes time and a steady hand. I've ported/polished around a dozen of these things.
