Interesting. I have ordered the PPK1 and will have it installed on my e90 335i on August 19th. I'll post my thoughts too. One thing I have read is that the performance seems to get a bit better after driving for a few miles. Not sure if this is true or not. I can tell you that it took 500 miles or so for my golf-T mod to really be noticeable. I have no clue why that would be. But it sounds much different than when I first disconnected the solenoid...esp on cold start-ups. The car really rumbles now.
