Iirc the cam timing actual and cam phase position should be as close to 0 kW as possible ...kW just means degrees of cam rotation , so if these data blocks are off it sort of proves that cam timing is off ......and the low engine vaccum supports this also ....yes this could also be a fault with the cam chain variator units ( yes known issues on these ) but you also have to know that your base cam timing position is correct also .
