Upgrade to High Flow Throttle Body??

[CLiverman]

Has anyone upgraded their throttle body? I've seen larger throttle bodies for 330's. One in particular from Dinan is 3mm larger and increases air flow by 9%. More Hp? Here's what they claim...
Peak Horsepower Gain..................6 bhp @ 6500 rpm
Peak Torque Gain .......................5 lb/ft @ 6500 rpm

Any thoughts?

Thanks,
Cory

yeah i got the dinan throttle body, high flow CAI and the chip for my 2001 330i. correct me if im wrong but i think that you have to get the CAI and the chip from dinan before they let you buy the throttle body from them. anyway i got all these three things installed at once and i can definitely feel and hear the difference. according to dinan, these three upgrades should be good for about 20hp. under 3000 rpms, i couldnt feel any difference except for the whine from the CAI (it makes a sucking noise). the chip is supposed to improve throttle response but BMWs have pretty good response as it is so i couldnt feel the difference. above 3500 rpms though, the car is a completely different machine. you can definetely feel the extra 20 horses. the throttle body makes a nice low pitched roar too! ive had these upgrades for about half a year now and theyre great. i recommend these upgrades if you dont want to void your warranty... but dinan is pretty fuckin pricey though.

xs3x over at e46fan. recently got at technik TB. he loves it, he has a review up at both renn-sport and e46 in the general so check it out if you'd like..

The TB has made a difference in power and torque, in addition to the CAI, exhaust and stage3.

Thanks to all for the responses. I've got the Dinan CAI and software upgrades. I guess the TB and the new UUC exhaust are next.
Anybody have the new UUC yet?
