The summary at the top says it'll be for the N20, but the actual article makes no mention of it. As we know the diesels are getting the PPK first.
I personally don't believe they'll have a PPK for the N20 since the boost is already so high. The N54 had a PPK, and the N55 in the E90 has a PPK, which is safe to say the F30 N55 will have a PPK.
N54 Boost = 7 psi
N55 Boost = 10 psi
N20 Boost = 16 psi
