That is what they claimed but has anyone with their kit that has done an independent dyno ever achieved that? If so, it would be news to me! From what you wrote the numbers do not add up.
Boost is back pressure. The stock exhaust is as restrictive as it gets. When you relieve back pressure in a force inducted application, you have a PSI drop off but you pick up torque and power.
Now it seems like this SC is capped @ 8 PSI. What that tells me is that no matter what you do to it, it cannot move enough volume to move more air than 8 PSI.
Put the larger stage II or III head unit on it create more volume and turn the boost up, period!
The garbage idea of leaving a stock exhaust on a force inducted car is one of the most outrageous things that I have ever heard...
