I have some serious questions about tuning DI motors though:

Where do I source larger injectors? To my knowledge, there are no aftermarket DI injectors I can buy off the shelf. OEMs only sell stock flow rate injectors.
Has anyone in the aftermarket successfully tuned this Toyota dual-injector setup? All the cars I see using it are not tuner cars, and have no tuner following (all the *FSE motors seem to be JDM).

I love GDI, but this Toyota-specific system has me very worried about tunability.
