Anyone got time to through a comment in here please
 






Well, I don't know about identifying them. I would assume you would need to take it to a shop who can test them and see what they actually output.

As for your computer not recognizing them, did you have your MAF or ECM retuned to match the new injectors? I believe you can either have one or the other tuned to match the injectors, but if they aren't tuned to match, your vehicle won't run properly as the engine doesn't send the right signal.

From what I have read on this site, it's not the maf that has to be changed it is the ECM that has to be made aware of the change of injectors. No one hear can do this.
