If yes, then the 2017 are not faster because most of the gain is better header and tune in the stock 2017 vs stock 2016.

Nope. They are bone stock because of regulations. In fact the engine and the ECU are sealed and no-one can touch it. Same for the exhaust.

Given the revised, more aggressive final drive on the 2017 cars, it's not unexpected to have a lower overall top speed given the roughly same peak power output. That would more than make up for the difference...
Plus, do you even know what tire compound they are running? They make the biggest difference and often are subject to series sponsorship.

I would agree with you if there wasn't a limit on top speed. In Japan these cars are limited to 180km/h (112 mph) by a speed limiter.
There wasn't any serious change on tires.
