Mods done, results inside
Well, all my so far planned mods are done and all my money is gone 
, so without further adue, here are the results: Stock with just a halltech stinger my car dynoed 319 RWHP. I was actually happy with that. I had a cam, underdrive pulley, LT headers with high flow cats and even a LS6 intake. Before the LS6 was put on the car did 371 RWHP and after the intake it was 375. To be honest I was expecting more, I would appreciate everyone to comment and please don't hesitate to ask any questions.
For the record: car is a 2000 6-speed and was computer tuned(not dyno tuned).

Running the MTI G1, a little "lopey" for me, should have done the stealth, but hindsight is 20/20 they say.
On that intake - I though I would get more too, I was told @ 15hp but only got 4..... They forgot to do it(the intake) and dynoed it before, then put it on and dynoed after so i know it is just from that intake. I can try a vid for sound of that cam, if interested, let me know.

looks like your are being held back with the LS1 heads. you cam wants air! try a set of Z06 heads or AFRs. youll make over 400rwhp easily!

You've got some potent parts there...
You have some untapped potential still by replacing the heads. Your not using all of your cam. What you have is kinda like trying to breathe threw a 50 ft garden hose.
The stock heads are also holding back your intake... your not realizing all the benifit because the heads are flowing less air then the intake can provide.
This is just a guess... (there will be about 12,430 opinions on these numbers). Add your stage 3 heads and you should be around 420-430 hp.

So would it be worth the $$ to dyno tune? Does the Computer tune need to be done (with the dyno tune) or did I waste the $$ on the computer tune, should I have gotten the dyno tune instead?
