When will people leave the whole IM and TB thing on fairly stock engines ALONE!!!!
YOU WILL GAIN ***K ALL POWER!!!! WASTE OF TIME.
Don't believe me?? Go to the dyno with your wanky 9000mm throttle body. Do a run with the OEM one then do one with the one 9000mm throttle body and see yourself how much power you don't gain.
Throttle response will be improved and you will "think" you have more power due to the fact that you don't have to push your foot down as much to get the same amount of air in then the smaller TB. But go to a dyno and you will see that on a mildly built engine you will gain 0, I repeat 0hp.

PEOPLE, PLEASE, LEAVE THE OEM TB AN IM ALONE, UNLESS YOU HAVE A FULLY BUILT BALLISTIC N/A SCREAMER!!!
And no, having Buddy club stage 2 in your B18CR or ITR cams in a B16a does not meet this N/A screamer criteria lol
