Versions of PFS PMC
 

What is the difference between the "pink 6" version of the PFS PMC and the "pink 9" version?

I know that the newer versions allow you to choose between twin and single turbo setups, and you set the boost levels for primary and secondary turbos. The older versions don't allow for single turbo setup and you set the boost levels for the 4 major rpm points not for primary and secondary turbo's.

Where does "pink 6" fit into this?

Does it allow for single and twin turbo’s and do you set your boost levels for the primary and secondary or do you set the boost for the 4 rpms?

Thanks
