Um we playd that game last fri you ran one thousandth of a second faster then me , WITH my car NOT hitting 3rd gear...but you still LOST cuz you REDLITE!!!! 
Come on people ona turbo car an ls1 to a ls6 wont make a dime in power. the air is getting forced in there , no more differance there is between the intakes.
im gona try a few tricks and i get back at ya!

try blowing threw a coffee cup stir straw and then blow through a whataburger straw and see if there is a difference.

Your statement is true to a certain point, then it becomes a restriction.
If this was truly the case then there would be no need for the 9,8,7sec. guys switching out stock intakes to better flowing intakes.

If he's seeing 13# of boost with a restrictive ls1 intake, wouldn't he see less boost pressure going with a better flowing ls6 intake? Isn't boost just a measurement of pressure and not actual airflow to the engine. So in theory, switching to an ls6 could drop your boost to lets say 10#, but pick up 30-40hp at least considering n/a guys with heads cam headers see at least 20-25hp from the swap, I know I did.

I see what you guys are saying about the difference between a supercharger and a turbo. But I guess it's more like fuel injectors and fuel pressure.
55psi of fuel pressure into 28lb injectors will only squirt so much fuel, but 55psi of fuel pressure going into 60lb injectors will put in a lot more fuel.
So if the ls1 intake is a restriction, or his exhaust manifolds or downpipe, it doesnt' matter if he's making 13# of boost or 30#, it's all about how much air he can flow through the motor at any given time.
If I'm wrong correct me, because I am no FI expert by any means, just trying to learn and think things out.

I think you need more timing. I'm running a 346ci with a t-70 turbo and a 231/237 112+4 cam. I made 500 hp to the wheels with 6 psi. With a more turbo friendly cam I probably would have made more power. Until the tuner brought the timing up I wasn't making any power. I don't have a way of logging my timing but my tuner said I was at 23 max timing. The cam must need the timing, i don't know. I don't think my timings too aggressive, not getting any knock and I haven't blown up yet.

*THIS IS JUST AN OPPINION*
1) If your running a stock LS1 intake I would rip that thing off the car and run an LS6 intake.
2) I would run a Lingenfelter GT7 Camshaft 350-383-427 LS1, LS2, LS3, LS6 208/230 .554/.546 121CL
3) Your converter is holding you back on the dyno tremendously
4) Should be running 15* timing
I'm not an expert and don't claim to be but this is my oppinion after years of being a forced induction techie

I am far from a turbo expert by any measure, but it seems to me you have quite a few issues going on with your setup, all of which have been addressed here in this thread.
like said...
1. dump your manifold. Get a Vic JR. Your LS1 intake is a huge restriction on NA cars, on a turbo car it is like trying to blow through a straw. ****-can that thing.
2. fix your tranny issues. You cant dyno the car accurately with a tranny that is slipping and ******* up left and right.
3. Up your timing\fix your tune. Like said by many people, your level of timing is very low. Something is very wrong in your tune i would bet. Ooorrrr, it could be that due to your whacked out intake or other issues your tune can's be set correctly.

You sure about that? Doesn't look right. Wastegate allows XX psi of exhaust pressure before it pops off. It has nothing to do with what is happening on the cold side unless you are running a fancy boost controller that is actually referencing manifold pressure (via a MAP sensor) to regulate the amount of pressure put to either side of the diaphragm.
Yes I am sure. The exhaust pressure does not actuate the wastegate valve...the reference ports on it do. Want proof...go pull the reference line off your gate and hold on, lol.
With a supercharged car you have a fixed amount of airflow. If you do anything to the motor to help it breathe better you will see less boost and the same or more power.
With a turbocharged car the wastegate controls the boost. The wastegate works off of a pressure reference. It does not care if it is on a stock ls1 motor or a 408/big cam/nice heads/sheet metal intake. The wastegate will still operate on pressure. The motor will be flowing a **** ton more with the larger motor but the wastegate/boost control system will still try to achieve the same boost.
P.S. I'll be in the minority, if you dont have the money to spend on the intake then dont worry about it. I've switched from a ls1 to a ls6 intake at 650 rwhp and it only made 680. 30 rwhp is 30 rwhp but with turbo's sometimes 30 rwhp can be cheaper then $300-350.
