injectors stock or not?

[C5T]

is there a way to tell wether or not your injectors are stock or aftermarket, my car at high rpms is dumping too much fuel in the 1st and 2nd cylinders which cause's it to sound like a subaru and die

Pull 'em out

can you tell when you pull them out if there stock

Open your hood, look at your intake manifold, trail the intake manifold runners down till you see a silver rail aka fuel rail. In the fuel rail, you'll see 4 connectors connected to your fuel injectors, if they are blue then they are stock.

But anyway, the high fuel problem looks like an ECU problem.

Check for boost/vacuum leaks
