I am doing my injectors DIY (balancing and such) since a long time.
I have a 603...fine engine... and I was increasing the pop pressure from 140bar( spec) to 145 and now 150bar.... and set timing 1 degree earlier relative to spec.... 14 vs 15 degrees according to the light method.
What do you say how much advance in degrees would be correct in order to offset increase of 10 bar pop pressure?
Best, Martin
