Without spending a lot of money on an aftermarket intake for 7-10hp, I don't think your missing power in the intake
ported heads might help, LS3 heads might help peak power, but will show losses under the curve for what I've seen in graphs
what's the current compression ratio and how much timing can she take? What head gasket thickness and LSA on the cam?

Tranny 4l65. Mileage ? You running stock convertor , If so 1st upgrade you need to do.. stock convertor can have as much as 20% slippage its TBSS running stock rims tires or big heavy 22-24s , Heavy Spun weight kills Dyno numbers. Your 384whp is no bad. I’m running 6.0 w 821 heads with BTR 226/240 supercharger L96 intake @390wph. Thru 4L80e w/ stock convertor my tuner guess my convertor slippage is 15-18% Good convertor will be in 6 to 8% slippage ..
personally the TBSS intake is great for street, the only good upgrade is $$$ Fast intake ...
What you have for exhaust?
