Dont just take my word for it....do some homework. There are plenty of threads that discuss how weak the stock LS2 intake is....very similar to an LS1 in power out, both of which are 5-7 softer than an LS6 even though the LS2 has a larger TB (which is usually never the real restriction and the reason it doesn't help).
Use the search feature....lots of info out there discussing what you seek.

LG did a post on this exact topic:
As you can see, the area under the curve is far more impressive than the peak HP and TQ numbers would indicate. The difference is more impressive than some headers are in terms of gains. At 4500-5000 there is nearly 20+rwhp gained as opposed to those that would have you beleive the gain is merely 9hp. The TQ is even more sick.
Many were asking about the difference between porting your stock LS2 intake vs. doing a FAST install. I am happy to share the results with you.
Again.
Run #19 was the same 2007 LG Pro Long Tube C6 M6 with FAST intake manifold
Run #14 was done on a 2005 LG Pro Long Tube C6 M6 with a ported LS2 intake manifold.
As you can see there is a huge jump in torque throughout the RPM range starting around 3500 RPM all the way over 5000 RPM. At no point does it loose any HP or TQ throughout the pull.
LG Pro Long Tube headers + FAST intake, makes for a very potent package! Pick up a G5X series cam package to make for a Z06 killer!
