Yes, you'll want the PP equipped pkg for all the added auxiliary coolers that are not found in a non-PP equipped SHO.
It used to be, for the '10, '11, and '12 model years there wasn't much difference between the two (other than gearing 2.77 for the non-PP, & 3.16 for the PP cars).
But that changed in 2013 and subsequent years.
Speak directly to LMS. They are well versed in this platform and they actually make lots of go fast parts in addition to the tuning.
Good luck and enjoy.
