are the aftermarket throttle bodies worth the extra money??? i've heard some say yes and others say no...whats the general concensus??

Aftermarket TB's will provide some benefit if you're FI or you've done cams and headers. The stock TB flows well enough for most bolt-on mods so an aftermarket TB is useless without some mods that can utilize the additional capacity. Plus, they're prone to installation issues.

Unless you have hi flow heads, cams, headers,
CAI, Tune and 4" exhaust, the stock TB flows well
enough until the other hop up items are installed.
They are just headaches waiting to happen.
If you do get one, keep the OEM TB in the trunk
along with all the needed tools to reinstall it when
the aftermarket TB goes south on a cold rainy night
in the middle of no where on a date with a hot chickola.

your stock throttle body can flow 890 CFM, that's good for 600whp or so. that's if you're drawing air through it like on a kenne bell or a whipple setup. on a kit that blows through the throttle body like a turbo kit or a vortech kit you can shove even more power through it.

there should be some gains below 600whp, but they'll be fairly small until you get close to maxing out the TB. if they weren't drive by wire and so expensive it might be worth the money for 5-10hp, but even on my kenne bell kit it's only a 15-20whp difference until you run more boost. if I wasn't going to build the motor later and go for 700whp it wouldn't be worth the $500 now. on an all motor setup I'd be really skeptical of any gains.

thats cool...i have the cams and long tubes and delete plates...i know 300 or 400 isnt worth it for maybe 5hp...
