get rid of the hypertech and go get a real dyno tune. you'll see some good gains from that alone. next do some induction mods, like ls6 intake and a ported TB. should all put you around 350 rwhp.

you might even be more if you get rid of that hypertech...

That's exactly what they're all saying.

Get a real dyno tune by a "known" tuner.

Ls6 intake manifold.

It is the last thing I want to do, then my bolt ons will be full (for me).

I don't want to touch the internals on my LS1. 24k on a 99... not something I want to mess with till I need to tear it up down the road

Get an LS6 intake. And for the love of God....sell that Hypertech to an undeserving soul on eBay. I would lean towards a cam after the intake is ordered/installed.

My guess is that you are probably right at 330rwhp
