vw vr6 motronic 2.9 tuning for larger injectors

[magner]

hi i have a diy turbo vr6 i want to tune for larger injectors i have ostrich2 and vagcom for logging. i fitted 36lb injecters and fitted a larger maf housing and the car runs ok i want to fit even larger injectors ive searched to try find injector factor constant (krkte) but it seems impossible to find i have to find alternatives what is the best way to go from 360cc to 560cc injectors 55.5 percent larger do i lower the complete fuel maps 55.5 percent or do i alter the lambda map values 55.5 percent from 128 dec to 57 .... or what about rescaleing the maf table what is the best way to go any advise please
