Jason and Rob: Great to hear about the AP release for the N55, two questions please:
1) What are your thoughts on running the Aggressive mapping with California (and NV/AZ) 91 octane while doing data logging? For those of us living in CA, this will be our first question.
2) Do you believe that the Sport mapping is similar to PPK?
