The intake and TB is the same from L99 to LS3.

Are you talking about porting the intake and throttle body?
As far as the trunion upgrade 6 say yes, and a half dozen say no. Kinda like the oil pump upgrade.

I would recommend porting the stock LS3 Intake and Throttle Body over investing in a Fast102mm and Nick Williams 102mm throttle body...
the ported stock parts flow nicely... Katech dynoed a BER ported throttle body and LS3 intake against a Fast 102mm Intake and NW 102mm TB... the Fast/NW combo gained 8whp and 7 ft-lbs... the BER ported stock parts gained 7whp and 5 ft-lbs.... and that was on a heads/cam car... so while neither are big gainers, spending $1500 on a Intake and Throttle body is pretty pointless when the stock parts ported can give you similar gains for $500 in porting
