94 regal chip needed

I am installing a 3800 supercharged engine from a Park Avenue in a 95 Chevrolet Monte Carlo. I am using mounts computer and harness from a 94 Buick Regal. It is almost a direct plug in except for the catalyst O2 sensor which is an easy install. The only problem I am having is trying to find a custom prom. The regal was a 3800. Can anyone help me with this. I have tried many places with no luck. If any can help email me either a website or other information. [email protected] Thanks for the help.
