Throttle body rec?
'02 LS1 with a V3-Si about to go on. Currently have a ported TB on there with the drilled hole through the throttle plate (done back in '02 before idle tuning was sorted out). Car runs great N/A since I tuned it with EFI Live back then - no idle or running issues.
What would be the recommendation on the TB in this setup - keep current or swap for something different?

If it works good na. Leave it. Most around here dont mess with bigger throttle bodies if it gets swapped usually just a 90mm tb. Id like to see if there's anything to be had with a 102mm tb swap.

I've heard that they were hard to tune and that they didn't offer much of a performance gain over a 90mm TB. was that 5 HP gain on a N/A combo?
I'd like to see the difference on a healthy 400+ cubed FI application though.
