Where am i losing power
I have a 98 ss with a crane cam 208/216 530/530, ported my heads and intake slightly, hooker LT's with y pipe and no cats and gmmg cat back. The problem is my car is only doing 313 rwhp and 366 rwtq 2 days after installation. Will a dyno tune help? what kind of gains can i expect from a dyno tune? want the Hp that im missing ..lol help

Well for one did you flow test your heads. I am sure you researched a little before you put the grinder to them, right? Another thing is the porting of the intake, very,very small gain if any. Tuning the car could gain 25 or 5 depending on the heads, good port job or a cluster job. I ported my heads but have been doing it for 10 years now and do a soso job, usually in the 27x range. So the heads may be whats holding you back or just a good tune.

All talk is BS and speculation before a dyno tune. Once this is done, then you can finger the weak spots.
IMO a LS6 intake will give you more horses than the ported LS1 one. Also I do not see a ported TB.
So if I were you, I would get those 2 and dyno tune. You should see 350>360 horses.
