325 standard Trottle body to BBTB How much gain is achived?

[haffeel]

Simple questions folks.

How much gain can I expect by replacing a Standard 325 throttle body to a BBTB ?

I have upgraded my engine from a 320i to 325i, still using the 320 throttle body.

Now that I have found a complete Inlet Manifold with 325 throttle body, I am ready to do the swap, including he 325 Fuel Injectors.

I am thinking is it a good idea to fix the BBTB now instead of using the 325 standard throttle body or is it a waste of good money

Oh yes, I am using ZONE CHIP.

Ant r u there M8 ?

Had mine now for about a month now, definitely noticed a difference, its more responsive ive lost that slight drop in revs you normally get when you put your foot down before they go up, if you know what i mean ( all my past 325's did this ).

feels quicker and smoother, worth the money !
