Sorry to bring back the thread from the dead but I have a question. How much would the powerband and power be changed (estimate) if this setup was changed to an S475 with a 83mm, 1.0 a/r, and a T4 setup? I am interested as I have been doing research on the S475 turbo on a 5.3 using a beefed up T56 setup.

In your opinion would the Quick Spool Valve drastically reduce the RPM range for full boost on the above mentioned setup?

Thanks in advance.
