We'll see what map strategy the Subaru guys used and see. As this car don't have a "sport button" that I'm aware of, the throttle maps and some other values will be improved by a remap.
Ferrari 458 excluded (The 997 GT3 is still indirect, right?), how many direct injection engines do you know that go past 7500? Usually they stop at 7k.

Subaru traditionally run an open and closed loop control but we'll see what the Toyota involvement brings to the table. I imagine the D4-S system has a split map with interpollation of crossover between port and GDI injection. We have similar mapping features here at work for similarly overlpapping components.
The new GT3 and Turbo models are GDI. Bosch motorsport units support 5-digits now, such as the MS-4 with HP5 pump and their injectors. I'm not sure what Denso injectors can support currently as I don't have an 'in' with them.
