Just stopped by dealer. 750.00 for the PPK1 software upgrade plus 160.00 for a labor charge. They said the car would need to be there from 2-8 hours to do the install. Said reason was I case there was other updates to the BMW software other than the PPK1. Paper work says you get 20hp and 32tq. So that would give it 320hp and 332tq. Is it really that noticeable from a stock 335i? I do have the sport package. Just wondering before I drop 1k and not have my ride for the day. Thanks
