Thanks for explaining. So in terms of end result, does it really make any difference? I mean it sounds like it saves time on the dyno, but doesn't really make a difference to the net gain you end up with. Am I right?

One thing that I would like to point out is street tuning. I don't know about the cobb unit, but with something like Osiris(end-user tuning option)+Cipher, one has all the tools necessary to make the ultimate street tune. After all, even the most sophisticated dyno is nothing but an approximation.

With something like Cipher, one can log with ultra high precision how long it takes to accelerate between two given speeds in a given gear. Make some adjustments, and make another run. The cipher logs should be precise to the ~10 millisecond level.

I don't know what the logging capabilities are of the AP unit.

I'm not sure how pro-tuners are doing it with the nissans, but when I got my pro-tune for my suby with the accessport, it included the dyno tune first, then the street tune to smooth everything out afterwards. Makes more sense to do it this way because there's no way to get a good tune if you're only doing one or the other.
