Could always pour to bump octane. It'll be a little harder on the cats, but FI cars are anyways. But lets be honest, how many opportunities do most of us have of hitting our max power on the street anyway? Once or twice in a drive safely? If he's at a track day, he can find a race gas pump somewhere and mix a little to octane up for some knock resistance.
Unfortunately there isn't much to be done about IAT's other than building a great heat exchange setup. Getting the hot air off the intake will be paramount right next to cooling the air charge as much as possible. Build the car to shed heat and go with a custom air to water intercooler, about the only way to get consistency without relying on ethanol to do the dirty work.
As far as getting around CA emissions, I still think tune swapping is the best bet. Procharger has been selling 50 state emissions legal kits for the 6 gens for a while now, I can't see how it wouldn't be recognized. As far as flash counts, burn that bridge when you get there. As was stated, if the flash count burns you, then you won't have a choice but to run a second ECM. What's scary about CA is they have the Smog Gestapo running around with mobile emissions testing units. You could get profiled by a clown car, pulled over, get the 4th amendment beat out of you, and then emissions tested right there on the side of the road while the tow truck waits for his signal. Not sure if they'd tow ya immediately but I can't imagine driving away without a fat fine of some kind.
