Small twin turbos with low inertial mass that spool up quickly and are intended to complement the engine's own volumetric efficiency with a moderate amount of boost.......not ram 22 psi of forced induction as the primary way of developing power.

7.3 PSI in terms how people normally discuss boost levels on this forum, but there is probably an over boost button like the 335is and 1M.
If this motor was under 22PSI in normal terms, we'd be looking at least 700HP given the displacement.
