Is 58mm Throttle Body Worth It

Hi I have a 95 camaro that I will be getting dyno next month. My mods are
Advanced injection Ported heads,mild cam, super comp headers.STS turbo system,42lbs injectors,msd ignition. The car dyno 360rwh before turbo install. Anyway I was thinking of getting a 58mm throttle body, is it worth $350 ? Will It make much differance? thanks

ive heard you get nothing with it on a stock motor, but it helps a little with a built engine (sounds like your case)

Since you have boost, I'd get one.

On our local board a couple guys did a dyno testing with all sizes of tb's and they noticed like a 10rwhp 15rwtq gain with the 58mm tb.

I noticed a diff on my TPI motor. I have yet to install it on my 93, regardless of what my sig says lol. I did port my TPI plenum to beat hell though, so it had no restriction mating up to the 58 like a stock intake would.
