The Nitrous Pro Flow Programmable TPS Activation System allows the nitrous system to be activated at wide open throttle on fuel injected applications based on the output from the vehicle's throttle position sensor rather than a mechanical switch triggered by linkage. On throttle-by-wire applications, this is the only way to safely and reliably activate the nitrous system. This system is easily installed and programmed for use on virtually any vehicle with a throttle position sensor.
