Nitrous Controllers

A nitrous controller is an essential component for managing the delivery of nitrous oxide in performance vehicles. Instead of delivering a full dose of nitrous all at once—which can overwhelm traction and strain engine components—a progressive nitrous controller allows the power to be ramped in gradually over time or based on engine parameters such as RPM, throttle position, or gear selection.

These controllers improve both safety and performance by letting users fine-tune how nitrous is applied, which helps maximize traction and engine efficiency. Whether you're drag racing or fine-tuning a street performance setup, a nitrous progressive controller offers the ability to customize nitrous flow curves to suit your vehicle's specific needs.

Among popular options, the leash nitrous controller stands out for its flexible programming features and compatibility with a wide range of systems. Like other progressive nitrous controllers, it allows users to set start and end percentages, delay times, and build custom delivery maps—all critical for dialing in consistent performance.

Using a controller instead of a basic switch setup gives you much more control, reduces wheelspin, and extends component life, making it a must-have for anyone serious about using nitrous oxide in a high-performance build.
