i'm looking to get a tuner for a V8 persian gulf spec. car. they are called chevy luminas there.
they do resemble a monaro but they are 4 door, my delima is should i order the monaro software or the commodore software?

any help is greatly appreciated.

Is there any numbers on the computer, like an OS number? I'm not sure what you need but I think this might be a start.
