Why are you using 7 bar fuel pressure with 660cc/min injectors? That's enough fuel for about 500bhp! Injector resolution must be a challenge around idle?
K03-005 seems to be okay for 190-195bhp, K03-029 is good for 200bhp ish, K03-073 a bit more - maybe 210bhp, and K04-015 a touch more still. I can't comment on the K04, but the others worked well with a 268° cam in my experience.
