Electronic Part identification help!

Hello all. I am hoping I could get some help figuring out what kind of performance part the attached picture is. This little black box is attached to a wire set that comes up the passenger side firewall and across the firewall of the car. If you unscrew the box there is a computer chip in it with 3 dials. The car has a superchip that I located in the actual computer of the car, so I assume this is not a tuner chip but I am not sure. I disconnected where it was grounded and found the car to run a little poor so I know it has some impact on the cars performance. It’s definitely it a stock part. Any ideas? I recently bought the car with very little information on the mods from the previous owners.
