The point of this setup is to allow as much air to come in as possible and as turbulance free as possible. The gain depends and will vary greatly on your complimentary mods. Just putting it on stock car, you might not gain much. But with full exhaust and intake and tuning, you probably can come close to to 70%-80% performance of an ITB imo.

70mm is the max a stock throttlebody can be bored out to.
also, are you sure yours is bored out all the way thru? Not just the opening, but the entire passage and mated to the IM.
