Nope. There isn't one with the super-charger yet. I bought my 1st Impala in '99-'00. Even back then, I was hearing stories about the super-charger version coming out "soon". I'm glad I didn't hold off waiting.
I traded in my '00 LS for an '03 LS with the SAP. The SAP didn't add anything to performance, just the looks of the car a bit.
