If you get the indiglo background, you will have to tap into the ECU to compensate with the outside temperature and barometric pressure. It also automatically spikes and flashes when another ricer is detected nearby.... just like a radar detector...only this feature is called "fellow-ricer detector". The upgraded version is even better. Everything I mention plus a 20 "shot" of NOS coming from the unit itself.. but you have to overnight order the parts from Japan. Once you get the unit, you'll have to tap it directly into the injectors by drilling a whole in it. Make sure that you use the check valves so the NOS does not shoot back into your face while "V-TECH" engages. If you do not have "V-TECH", just tap it into the Motec exhaust system to vent off into the atmosphere... The cost varies.....
