injector flow rate ques for edit
Your going from about 26 lb injectors to lets say 36 lbs.
That is about 33% more flow with new ones
Subtract how lean you are so in this example
33-10 = 23% extra flow is left.
Tuning flow, the smaller the values are then the PCM thinks the injectors are smaller and goes richer, the larger the value, PCM thinks injectors are larger and commmands less fuel.
So in this example your 23% too rich so increase the values by using the multiply command of 123 which is a 23% increase in values, thus would be 23% leaner scaling across the flow table.
I do not suggest mucking with offset, if the injector your using is also a Bosch Multech II design then the internal coil is the same as stock was, you use wrong offset value and that could mean the injector now fires too late after plug coils have been commanded to fire.
