Would anyone kno wat is the differences between the two(I kno frpp is more expensinve) any more gain in hp in one more then the other, installation is one more harder to install then the other...I'm asking cus I'm guna install new tb on my 09 gt, but I'm stuck on which would be best on my car I got a c&l intake, bbk shorty ceramic, bassani ss xp, borla stingers, and I got a sct x3 tuner

Unless you're FI or internally modded, any of those TB's you mentioned will provide no HP gain. The stock TB provides as much flow as a NA and non-modded engine can handle. Not to mention the install issues that an unusually high percentage of forum members have had.

Agreed about it being worthless without a supercharger or some heavy mods. I installed the BBK throttle body in about 30 min with no issues though

IMHO, the BBK is crap, and has had a great reputation for that. Like Nuke said, unless you are FI, both will net you a 0hp gain. I have actually seen an 8 hp loss with the BBK on Doug's dyno on a "stock" gt with a tune and cai.

BBK is crapy. I have one, granted im in a V6 but the thing has caused problems with the running of the car. If you do get a TB jsut stay away from BBK.


(Havent had a day to take it off yet but damn i need to)

idk maybe its just since im f/i lol or i just got lucky and they gave me one that works hahaha

i think that you picked up that extra 12hp cause of temperature differences or different air conditions. I have had multiple tuners tell me that the only FI vehicles you are gonna see an honest gain from the TB is a positive displacement blower. Our Centri's wont benefit from a bigger TB

idk our temperatures and humidity are pretty consistant here
