[2004PTlite]

I recently bought a 2004 pt for the wife. The previous owner had some parts that went with the car and in them was computer that say Mopar Peformance Stage 1 turbo.
From reading on here it looks like it is re-useable on another car..correct?

What is a fair price to ask for it used like this or do I just put it on ebay and let it go??

Thanks
