Wrapping yourself around a tree is a potential danger.
Reply:The same engine you have now will be producing more power so the chip will cause more wear and tear. It depends on what the "chip" is designed to change if you want to know what specific parts will be affected. You will also most likely void any warranty you have on your car when you mess with your ecu.
