You should put the LS6 Plenum on it. It's an honest 10 to 15 hp boost. This is a great mod for the LS5. Cost I think is around $500

http://www.slponline.com $399.00 for the complete setup.

It's about $530.00 through the GM dealer and you have to order the two coolant block off plates, and the coolant line needed.
