I've read similar assessments from the E90 owners who had it done...
However, the Dinan tune seems to be more "impressive"...
For me it's a cost/convenience thing...if I move out of the area, I'll probably get the PPK. If I stay near my current dealer, I'll get the Dinan.
Interesting. Thanks for the info. On the same boat as you, need something convenient to my location.
I'm assuming both the PPK and the Dinan tune won't mess up comfort mode and eco pro correct?
