L99 is an auto but technically still is a 6 speed. I only counted a 10 hp gain. I'm assuming that's what you meant.

Edit, never mind, you were talking about specified RPM. I see that now.

2010 2SS/RS Auto, Sunroof, Engine Cover. Transformer Edition package.
2013 ZL1 ragtop #5478. 1 of 54 CRT M6 'verts.
