I am not sure if I can help answer your question but I can give an idea.
I have a 2001 WS6 which is basically the same as a 01' SS IMO.
I had SLP lid and K&N filter with street tires (with a clogged cat) and I pulled a 13.2 @ 104. I am sure others have done as well as 12.9 with the same. But, many more have probably done slower times.
Anywho nice ride and enjoy.
