58mm throttle body with a procharger?

I have a procharged 93 lt1 running 9lbs of boost.It runs 11.60s.I have a 48mm stock throttle body on now. What kind of gains do you think i would get by going to a 58mm throttle body?

I saw very small gains. But every little bit helps. It was one the best "appearance" mods I've done yet for the engine bay. The Holley 58 is the one I went with.:)
