Generation IV External Engine - ls3 throttle body question....

I swapped an ls3 and t56 into me 65 impala with a holley hp efi system and a custom ground predator camshaft..My question is, im currently running a victor jr intake with an aarons sheet metal elbow and a nick williams 92mm throttle body.. with not being a forces induction set up am i losing power? And should i change to a 4150style throttle body?

Ditch the elbow and get the 4150, as long you are staying n/a.
