I did this mod a couple weeks ago, I didnt even see this write up on here (I strongly agree if TBI upgrade is a sticky, this should be too) I saw some guy on you tube do it.
My air intake tube was all messed up so it gave me an excuse to buy a volant Intake, i put that on, drove around for a little bit, i felt a little smoother acceleration but at the same time I thought I could be "wanting" to feel smoother acceleration. anyways took her back, pulled the air intake off and pulled the throttle body off. I took the butterfly valve off and shaved the lip off with a dremel and a cutting wheel bit attached. thought it cleaned up real nice, then i took a drill powered wire wheel and a wire brush and some carb cleaner and cleaned the rest of the throttle body up the best I could. put everything together, and took her out on a cruise.......I immediately noticed greatly improved throttle response... I wish I had known this 9yrs ago when I bought her, I would of done it then. Personally I think its a great free upgrade.
Good Write up Vortec Lover. It should be stickied, more people would see it!
