you do not absolutely need a new chip for it to work but a chip will drastically help performance. i thought that mine wouldnt start without the cold start injector, but it did and i havent had any problems with it not starting even in 20 degree weather. the only things that you really have to do are connect the stock fuel lines to the fuel rails and get a new thermostat housing that points in the right direction. do a search and you will find plenty of information on what you need to install the HSR and check out www.stealthram.com
