fast 78mm throttle body

I was just wondering how good those throttle bodies are and what kind of power gain they might give?

You are probably better off using a ported stock TB and you should save some cash.

Yeah, I payed an arm and a leg for mine. I can't complain about the power my car made (not sure how much was gained just from the TB since I did a cam too). Now I'm wondering if I should stick with the setup I have (LS6 and 78mm FAST TB) or swap to a FAST 90/90.

If $$$ wasnt a object, people should engine dyno all mods to see a gain.

While I agree with this statement its not that simple. Some mods are done at the same time and would require a LOT of rework to dyno each individual mod. (reinstall tuning etc.) For instance the UD pulley is usually done when a cam is installed. The TB is usually replaced when the intake is replaced and some folks go nuts and do everything at once. I wanted to dyno my car with the LS6 intake and Ported TB then add the FAST but it would have taken too long to mess with everything.

Don't worry guys, when I'm rich I'm gonna get a dyno and spend all my time dynoing different combinations, lol.
