Pull the chip and then install a socket to connect an emulator instead. You can tune all you want, and in real time too. Check out moates.net for equipment.

your talking about the roadrunner right?

yes.

You could probably find some other generic emulator if you really wanted to do it yourself.

You can reflash 411 PCM using AVT cable and Dimented's Flash tool.
