A bolt on 5.7 can make that LOL. Honestly, I think it's just a lowsy, mismatched setup. Something major is up here especially at 10 lbs of boost. I really don't think we have enough info to help you out with the problem. And I think I remember you saying you didn't have a boost gauge?? A boost gauge is like $70! Get one on there and you'll know what your making for boost, not just relying on the tuning software.
You using stock plugs or have you gone colder? Not revving past 4800 leads me to believe you have a major ignition problem. Any CEL?? Are all the coils actually firing? The turbo is not going to magically make the car not rev past 4800 so check all your basics first.

can I go 15psi boost with my combination? I have already ordered the valve springs and a new oil return pump... would a 67turbo be efficient at 15psi? i need to make 500rwhp
First off, as others have said you have too much fuel, even 10.3 is rich without meth, when using meth you need to reduce your AFR even more since the Meth is essentially a fuel as well(11.5-12 AFR when the meth is engaged) For FI motors I tune them to around 11.5 (without meth injection) when at 10 psi and go from there and start tweeking the fuel and spark until the power goes in the right direction (MORE!!)
Your numbers are way low for what you have, and I think it has a lot to do with too much fuel, try turning the meth off and lean it out till 11.5 and see how she feels, I am willing to bet it will feel much faster...

Update: I have ordered the comp cam valvetrain upgrade kit with solid lifters, a new 15psi wastegate spring and a 3600stall torque converter.
I have two options
1 100HP wetshot of NOS
2 go 15psi of boost.. and maybe some NOS
im open to ideas.. im preparing the car for the open day at the track

Not to mention 15psi on your cubic inches on the stock STS turbo is BEGGING for a KABOOOM. That little guy would have to spin to hell and back to push that much air if it really is just a stock STS T60.
Please do yourself a favor and find someone locally who has a bit more knowledge on this stuff and get their help. And I mean that in the nicest non-******* way.

well I am suprised knowone has mentioned a compression test or leakdown test.
that hp lvl is super low my ws6 makes that exact power with nothing but a intake and a tune.
I would say its more than just a buying other parts and slapping them on there thing.
but truthfully it does sound like the OP is not sure what he is doing, why order solid lifters? lifters is not the issue here the stock ones wont rob you HP, and if theres no noise from the valvetrain then why bother with that till you fix the primary issue.
I also thought 317 heads were higher compression than ls1? not the other way around.
here is the thing, if you are working on the car yourself, you need to just take it to a shop, if a shop is doing the build take it too a different shop
also if this was a junkyard motor I hope you went threw it and tested it out before you just threw it in. you need to include a little more background.
if I had to guess your over 150 hp to low and there is alot of issues going on here.
but I also belive you have a horrible setup on top of it, I would recommend a cam change and get a cam thats ment to run with a turbo engine that will make the valves operate at the right times and intervals to make sure your not losing boost from them being open.
