As enthusiastic as everyone is for the AP, Cobb is probably setting their priorities right, the 350z / g35 market is BIG. Seems to me like every schmuck is riding around in some VQ powered monstrosity. Even if only a fraction of them went with an AP, its probably still more than the tiny little MS3 customer segment.
So yeah, it does suck that its taking so long to come out, but at least they're making stuff for us. I'm sure a lot of people are going to get sick of waiting and either go with cpe or the manual boost controller route. Once cp-e releases their PnP harness they're gonna sell a LOT of piggybacks.
