Why not go the Dinan route? I mean you'll lose your "CPOabilty", but Dinan matches the BMW warranty, and you'll get more power than with a PPK.
I had the PPK and I was unimpressed.
It's just a thought. I love my Dinan stage III.
The only trouble is, it isn't cheap, and for stage III you do need the upgraded oil cooler and intercooler, which can easily take you into a few thousand. You can easily do stage II without any further hardware upgrades and it will provide more torque and horsepower than a PPK.

Peak Horsepower: 355 @ 5300 RPM
Peak Torque: 401 @ 3500 RPM

Stage 3:

Peak Horsepower: 373 @ 5300 RPM
Peak Torque: 408 @ 3500 RPM
