I don't understand the basics of what the chip 're-programs' HOWEVER, I am interested in the inquiry as to the impact on the engine or other engine part's longevity. Also, as Eric asked, do these chips cause additional heat issues with the 500E?
I received my first catalog from Precision yesterday so I have a heighten interest in the chip!
