The difference is probably down to environmental factors - I don't thing it has been specifically tuned to give more or less power in one continent, more tuned to better suit the environment in each continent (heat, humidity etc)

At least here in the USA, I wouldn't be surprised if EPA/emissions regulations played at least a small factor.

 

[Ulti-Resis]

Oh I'm sure the emissions regs are playing into all this, no doubt at all about that!

 

[Pierito]

It's likely a combination of emissions regulations and fuel quality.

Looks like you can get +33 hp on the FK8 with 91 octane using one of the Hondata base maps

I really hate those small turbo torque maps that peak and fall of a cliff. I like how some tuners might give you less peak but flatten the curve the car feels more progressive and normally aspirated.

If it was up to me, this car would have a factory 9,000rpm K24 with individual throttle bodies (like an old BMW M engine). Alas, those days are gone forever, so I'll begrudgingly take the turbo 2.0L.

They definitely would.

K24 with ITBs is that slow?

In top end, no, but it likely still wouldn’t make as much torque as an L15 turbo.

 

[Z3N]

As long as the turbo doesn't kick in late (looking at you WRX) I'm good.
The short rpm boost in most modern turbo intakes is fine by me; good economically and for fun.
