520D Steinbauer

[Dean83]

Hi all, I've had my f10 520d b47 for a couple of years now and am about 6 months from the warranty end period. It's a great car for my long motorway journeys, but I would like some more power. A new 530d would be nice, but probably a year off that right now. There is no PPK for my engine, but Steinbauer and ACS have options. Given I'm nearing the end of my warranty period the ACS option seems unnecessary and so I'm looking at the Steinbauer.... has anyone any experience with this on a 20d engine. How would you rate it?
how is the power delivery? Did it change the engine refinement (despite a diesel, the b47 is actually pretty refined for a 4 pot)? Any other points?
Thanks
Dean
