Nitrous Express Maximizer EZ Progressive Nitrous Controller (16006) - High-Performance Nitrous Oxide System for Drag Racing & Street Performance

If you have nitrous on your street car or any car other than a serious race car this is a nice piece for the money. Would work on a race car too but for more serious stuff I’d recommend a controller with more settings. But for a small shot this thing is awesome. Easy to install and even easier to use. Just plugs in where your relay is now. To use just turn the dial to however many seconds you want to delay the nitrous in 1/2 second increments. It starts at 50% and brings in the other 50% over the selected time you set on the dial. Really helps with traction on slick surfaces you dial it for a longer delay and your kit won’t be at full tilt until the car is hooked up and going. Awesome for $150
