Ask Katech, the people who build the C6R engines, what more GM could have done to the LS7, but still kept it 50 state legal.
GM didn't leave much on the table with the LS7. Although a tune can unlock some more power, it's at the risk of increased cylinder head temps (due to leaning the AFR), among other things.
As I've said before, fewer cubic inches and forced induction is the wave of the future. The LS9 is just the start. We already know most of the future LSx engines outlined thus far are slated for supercharging. It's the only way to get the horsepower and still meet future C.A.F.E. and emissions standards.

I know I've always revered the rule "no replacement for displacement"..but there's method to the madness. With a 6.2L motor...smaller cubes, they can twist this motor higher into the RPM range. Coupled w/the supercharger which makes the power band that much broader..so another words..w/the roots type supercharger, she's making power down low..Hence the "axle's on a more horizontal plane and steep 1st gear to launch the car" as they stated. Then twisting the hell outta the smaller cube'd motor, means she's still pulling hard up top....where most roots type superchargers will start to loose some efficencey..
Make no mistake..aside from some cosmetic differences and a stupid name...
THIS CAR WILL BE A PERFORMER!!!!
I'm sure the "power guys" at GM have pushed the limits w/pulley changes etc. etc..this LS9 has already seen 800HP!!! I gaurantee it...
