For a stock 08 96" RKC which race tuner is correct? The older 32107-01H or the replacement (as I understand it) 32109-08?

If I had my hands on a new 32107-08H is there anything I would be sorry about if installed instead of getting the 32109-08?

This probably belongs in a Tech thread but wasn't sure which one so I threw it out here.

Thanks!
