Default Tune/PCM swap

I bought a spare 96-97 PCM for my 97 Z28 and sent it to Solomon/LT1PCMTUNING for a mail order tune. I gave him the VIN from my car to load onto the PCM. Do I just swap the tuned PCM in or is there a Case Learn procedure? Not sure how that works since it was from another car. Thanks

After it's been flashed, all you have to do is swap it in. It might run a little bit wonky for a bit since the fuel trims and such are reset, but a short drive should have it back exactly where it was
