The guys who did the Dyno tuning in USA dind't bother to do that, so we spent two days in a chassie dyno to get the engine driveable...

I wonder if some of your tuning issues would go away if you regulated the pressure after the injectors? That way you would be guaranteed that all of the injectors are getting the same fuel pressure. It would also reduce heat soak related issues with the fuel in the rails. Or, am I missing something in this photo?

Love this project!!
