I've read that some people Have taken a dremel and grind their throttle bodies. Is this worth doing for any gains or improvements. If So can someone tell me what I need to do, to do this myself.

 

it is debated whether or not it even helps

when/if i swap to an LS6 intake manifold ill probably get a BBK 80mm TB ( already ported) im afraid ill screw something up porting it myself

 

If i do I'll just have an excuse to tell my wife for buying a new one LOL.
But i don't want to spend if i don't half too i'm a tight bitcccccccch. lol

 

I wouldn't grind on the throttle body,your truck's ETC is real sensitive to any changes.Ported throttle bodies and ETC seldom work well or at all.Don't do it.

 

all the guys on tech beleave in them. mine was done by shaners.

 

i didn't have any issues with my hillbilly home-ported DBW TB.

 

ive ported about 5 or 6 and they all worked just fine.

theres a good write up on installuniversty.com

 

theres a good writeup on the last page of my cardomain

 

I ported mine myself with a dremel. Its not hard - just takes time. I noticed an increase in throttle response but as far as horsepower I dont know. Here are a couple of pics of mine.

 

I ported my Z28 TB and found it was so easy the truck's came off the next night for the same thing. Probably picked up a ton more with the car than the truck, but it gave me something to do for a few hours one night.
