Hi guys,I know that this thread is kind of old but i do want to update on whats going on with NIStune. They did release a feature pack that now you can activate your vvl with NIStune via egr output just like tunercode and nothing against tunercode i did look at it but did not use it since its illegal and i am a nismotronic and nistune dealer they are both great nistune is a more affordable and nismotronic is just worth every dollar its just a matter of what you want or what you need.
