overkill 62mm itr TB???

[dupac->]

Just a quick one..

Mods --> b16a2
- 4-1 jdm itr headers
- plazaman/dynodave cai
- bc specIII 2.5'' catback
- metal cat
- skunk2 IM

with those mods.. would a 62mm ITR TB be suffiecient?

I'm looking at a tune later on down the track with better headers and afew other things aswell.. but not atm..

but for instance if i whack the TB on would it make a difference??
I'm not looking at any power gains or improve response doing this.. i just dont wanna LOSE power or response if yah get what i mean?

or should i wait til im ready for tuning or scrap the itr TB all together?

and also.. will a 62mm tb be sufficient enough for a tune with head work n shit done?

thanks Du
