How can you tell if your PCM has any mods to it?
Bought a 97 GTP.
It has headers, CAI, roller rockers(not sure about cam upgrade).
Checking for SSIC and other mods.
I have an Autotap scanner.
What should I being seeing on the scanner if the PCM has been modded?
What parameters can I look at that would be outside of standard outputs to indicate that the PCM was reprogrammed?
Thanks for any help.

Don't know much about this.. But I'd imagine you'd have an idea by looking at the list of things the aftermarket people do. Zzp has a list on their PCM page

Toss the autotap and go with HPTuners. In HPTuners you can compare a stock file with the file in your car and see exactly what has been changed and by how much.

I don't think you'll be able to tell anything from an autotap really. You need a tuning suite like HPTuners or even a Powrtuner (find a used one pretty cheap on clubgp).
