Default 1989 eprom superchip?

Hello to all fellow corvette enthusiasts... First time here but wonderful site.
I have a 1989 corvette convertible with 350 efi and automatic tranny. I have a question about the Eprom chip... Mine needs to be replaced so I removed it and it says "superchip" on it. No manufacturers name or other identification. So my question is does any one know if this chip is a stage 1,stage 2 or a custom print? And or what would be a good performance chip without being a custom print?

Welcome to the forum.
I think Superchip is the name of the company. I had one in my first '87 IROC-Z and couldn't tell the difference when I took it out.
