I was thinking about upgrading my throttle body. I just don't know what the best course of action is. Should I buy a throttle body from SLP or should I go with a CNC'd stock one? Which option would yield the greatest results? Also, is there anyone who can port and polish them for a fair price?

If you're talking about a TB for a stock intake, I would have someone port your factory one. I wouldn't waste the money on an aftermarket TB that will make the same power as a ported stock one.

I forgot to mention that I do have the ls6 intake installed with the EGR delete! I'm going to be getting the car tuned as well. Does anyone port factory throttle bodies?

Do a search for shane or shaner, does a hell of a job I think its called the S2 throttle body he's the only one I know that ports tb's that I know of then there is Janzter, and pretty sure some sponsor on here ports tb's.

Send your stock one to one of the sponsors to be ported.

i have only found one place that CNC ports them. i doubt in terms of horsepower it would be worth it. however, it is nice to know there is more of an exact science going into it than someone with a dremel.

Is there any noticeable performance difference or gain in horsepower? Also what does it cost to have a throttle body ported for those who have had it done?

Google shaner throttle bodies. His top package is about 125 + refundable core charge. And yes there is a noticible performance gain in most applications.

zmax cnc's them. I had one and they are very nice. Typically the benefit of a ported T/B is throttle response along with a few ponies.

This is what was in the PM.

I got mine through mikenorrismotorsports.com

I don't know why I forgot Mike was a sponsor on here. I don't know if VMax has a website or not. I thought they did but I can't find it.

Which website should I go with?

http://www.s2performance.net/ or mikenorrismotorsports.com

I want to get my throttle body done right and have it yield the best results!

How did yours come out?

What about a 408ci with ls6 intake? What tb and maf. Should I get?
What are the limits of stock tb and maf on a 408 anyway?

I have only dealt with Mike so I can't comment on the other. Mine came out great. It's a shame it gets covered up.

Here is a pic of it.

This guy is giving me a good deal. Think this would be a safe bet.

did they use epoxy inside your throttle body?
