Is there anyway to read injector pulse width individualy? Too see which cylinder is using more fuel, the engine managment is stock.

8-channel Osilloscope is the only way as the PCM doesn't report individual cylinders AFAIK.
On V8s it is bankwise control and I gather we do not
have the individual cylinder offsets that are on the V6
models?
For that to happen there would have to be O2's on each primary for the PCM to correct the fueling from. It takes an aftermarket fuel management system at the least to support even the PCM inputs from something like that.
Actually a close-in NBO2 can resolve individual cylinder
pulses with a clever-enough sampling scheme that
knows which cylinder did what, when. But I doubt the
GM PCM is so sophisticated. When you know each
cylinder's exhaust valve event time you can do it though.
At least at the lower RPM, before things start to stack
up in the pipe.
