The specialists for checking these is on here, I just cannot remember who they are and want to contact them again to send them a set to ballance them out for me also.
i don't have that info .. sorry. if you send em to me, and you tell me what fuel pressure you want em tested at, i can give you cc/ml per minute readings. $7/per for a "flow test only". Full cleaning service (including before/after flow tests) $19 per for most injectors.
Can you just supply injectors that are = Ballance so as to not have to send them to you from New Zealand for checking and ballancing??
