Added a Soler throttle controller to my SC’d LS2 about 4 months ago and it made a for a stunning increase in throttle response quickness. Well worth the $100 or so and 15 min install. Wish I knew about it sooner.

You can check for vacuum between the throttle body and the blower. There shouldn't be any at WOT. If there's much over 2" there you'd probably benefit from a bigger throttle body.... or a new air filter. You can rule out the air filter being the culprit by checking for vacuum between the throttle body and the air filter at WOT.
