Throttle Body Before & After Dyno Gains? Does anyone have just a throttle body swap and did it gain power?
What modifications did you have and a post of the dyno graphs would be great

Swapping the throttle body as an early mod is generally considered a no-no. 
The stock T.B. will flow enough air for most setups, and aftermarket T.B.s can be a bitch to gt running right. I don't know anything about your setup,so I will assume you are a stock or nearly stock LS1. Your best bet as a new comer would be to port and polish your T.B. and spend your money on LT's, exhaust, a lid, cam, suspension, ect. There are countless people on here that wish they had never Fu@#ed with their T.B. Just my experience for what it is worth.

Thanks Johnny C.
Just to clarify, I do not own an ls1, etc.
I was just trying to do some research on what actual powerlevel did the aftermarket throttle bodies actually make a difference.
Does anyone got flow numbers for stock throttle bodies or aftermarket throttle bodies?
Stock is 75mm right?

No LS1? I guess I should have seen that from your user name!
If you are speaking in general terms, then I couldn't really give you a H.P. number that makes sense for all TB's for all cars. Cars respond differently to TB swaps - some benefit more than others depending on the stock configuration and the setup.
