Yes, very informative. So I probably remember that wrong with the restrictor (but I'm sure the CNG car here had bigger one than petrol ones).
EDIT: According to MikeyD in R5 thread Basso's car has 32 mm restrictor. In videos it actually looks less powerful than the other Fiesta R5 so it might well be true. The worse news for Peugeot then and hat off for Basso.
