Injector constant is Grundanpassungskonstante, tune it using the physical formula.
You know the stock injector flow and fuel pressure, after you fit the new injectors (and/or FPR), recalculate the flow and adjust the constant. It is linear. Don't forget to adjust injector lag time.

I will take a look to maf flow and load values too. Maybe a bigger MAF will improve ECU resolution at higher than normal boost values and smooth transients.
