I have had a special factory Engine once i was racing karting. It was increadable. It had all the best parts in it. And was legit but it was an engine with the least tollerances it gave just that little extra to be champion.

Such engines they keep for factory drivers for sure.
I am sure there is an element of that (mostly software?) but they can't afford to offer the customers too inferior a product as they also have to compete against the other manufacturers, and R5s are meant to be primarily customer cars.
