Performance tune for '08 4.8i

I've searched but can't find any performance tunes for a '08 4.8i. If anyone knows of any and could point me in the right direction I'd greatly appreciate it.

Excellent...thank you! I'll look into the ESS and give them a call to see if they have different stages also. 10-15 hp is a little lower than most of the other tunes offered for other models and engines but it's a start.
