i learn something new all the time , how is the supercharger completely different from the last generation lsa ?The LT4 Supercharger is a Positive Displacement type of mechanism. It's more linear, interns of how the power is rely. Completely different from the last gen V2 Supercharger on the LSA. Look into the items(supercharger, valve, fuelline), discussed above. How I was able to determine the issues were through my own dudelgence, asking 'intelligent ol heads', own & know about how this type of supercharger works. Also, C7 Z06 forum, under THE STICKY'S, maybe helpful.
Good luck, keep us informed.

You will have no boost under "normal" driving conditions. The air is just recirculating inside the supercharger through the bypass valve. Once you move the throttle down enough, the engine loses it's vacuum and the bypass valve is closed by spring pressure and now the air is forced into the engine and your gauge will begin to read boost pressure. Gen III CTS Vs generate 9-10psi from factory.No. But even lower speeds/throttle should have boost right?
