That whole, "let's reflash cars that come in for service so the PPK seems worth it" seems a bit shady. ALthough, it does go along with my questioning, the exact gains that would be realized by the PPK. Since BMW has never released a dyno graph of a non PPK 335, and we know it's underrated at 300/300, and now we have a graph of the 'after PPK' saying it's xxx hp and xxxtq, what really are the gains? Is the PPK graph underrated also? If not, it's not much of an increase at all and probably not worth it (unless they start reflashing our cars to detune them).
Unless of course, the gains are truly gains above the underrated engine already... Ahh my head hurts. Can I have 350hp/350tq for $1k and keep my warranty?
