With all the places that build performance injectors how are thay identified? I know thay use new or used core so how do thay tell if the injectors are the ones that thay built as in marks or ID numbers?
What I ment is what is the marking. Is it a part number there name some form of ID and how to determine who it is. This would help alot of people if you buy a truck or motor and the seller says it has injectors it would be nice to be able to pull them and ID the builder and size.
