Stock fuel injectors

[Viper GTS-R]

How do I tell if my fuel injectors are stock or if they have been upgraded previously?

Those look stock. Why would you expect that the factory injectors have been replaced? Has your engine been modified so that you have increased fuel demand or have otherwise found the OEM injectors to be defective?

Car had work done by the original dealership. Headers, rockers, throttle bodies, etc.
I have since added a Paxton, removed the AEM engine management computer that was on it, put the
stock ECU back in and added a Split Second Timing and Fuel controller. Mark from Split Second is helping
with the setup and asked about the injectors.
