The modification i was talking about on the throttle body was to run the cup of the bottom blade of the butterfly. I did this when i had my 4.3 and it made a huge difference in throttle response. You just have to be really care when you do this mod to not cut in edge of the throttle blade. Ducky look on your throttle body and you should see what i am talking about on your blade.

What do you mean by run the cup?
