are the N55 mpg and torque better thanks of the valvetronik or the twinscroll turbo?
I would say that a N54 with valvetronik would be as good as a N55 but more expensive to build.
I saw in the german description of the engine that even the turbo lag Is reduced in the N55… after the mess on the N54! Easy they don’t have wastegte rattle to fix on the N55… so no lag introduced by the DME
Another money aspect, I think BMW switched from Mitsubishi (N54) to garret turbo in the N55, these are the same as the ones used in the X6//M... large scale economy????
