@Mightyman Nah the DTRE's were given full YPVS servos.
Although you make a good point, the YPVS does shut off at 10'000 rpm as a restriction.
But the point here is the build up of NoX's gases. So whilst they did shut off, the normal person would be part throttle anyway. And if you were pinning it, well you would expect it to give up eventually and this might be why.
