If you need something to compare it to, stock BINs are available for just about every car that had the 16188051 PCM.
Your 1996 LT1/4L60E combo was an OBDII, which while able to be tuned, is far more expensive to tune than 94-95 due to gatekeeping by those who know how to do it. The hardware and software to flash the OBDII PCMs is in the hundreds of dollars, compared to a $70 cable and $0~$20 software for the 94-95. That's why people swap the 94-95 PCMs on, since they're electrically compatible. However, if you're an automatic, then there's a good chance your PCM is a 95 because there was a change to the 4L60E for 95-96 that makes the 94 PCM get mad (I believe it had to do with a PWM signal to a solenoid). So, if we assume that your PCM came from a '95 automatic, you should start your comparisons with the '95 auto Camaro and '95 auto Corvette BINs. They can be downloaded for free here:

When you connect to the car with EEHack, what calibration ID is listed? If you're lucky, then whoever "tuned" your car (I have my doubts) left the calibration ID alone. If they did, you can actually download the exact factory BIN for your calibration and compare. I'm willing to bet they'll be identical and no actual tuning has occurred.
If you want to know what an LT4 BIN reworked for a '95 PCM looks like, here it is:

Best of luck to you!
