Tim,
yes I had the factory do the upgrades. It seemed a little unfair that they wanted the car back there rather than let the dealer do it.
I had the NVH (IMHO pointless and very expensive) the fan (Good if you are in warm climes or traffic) and the Comfort Pack! They noticed after changing the BB that the compensator was goosed. It needed a quieter BB to hear the bag of spanners moving about. The new Centa is not quiet but maybe better as long as you keep the revs on. I cannot say definitively that it is the answer.
