tnx Steve! Here's another run I found from that day:

Did a new dynorun today with same sort of problem as before: running lean up top...
Its not too small injectors, but since I can log fuel pressure as of yesterday, it showed that FP gradually deminished from 3,5 bar to 2,5 bar at 1,3 bar of boost. Even though I have a boost referenced fuel pressure regulator!
Lambda was approaching 1.0 again...and misfires occured.
I even changed the fuel filter on the dyno and gave a bit more max fuel correction (30 instead of max 20% before). Even though the run didn't misfire this time, it still ran lean (lambda 0.95+ but just rich enough not to misfire and the run ended in 418 hp up top (max rpm 7200). Atm, I think its too small a wire I used for both fuel pumps.

This was at 1,3 bar. I never got to my intended 1,6 bar...
