Time Based Progressive Nitrous Controller (Single Stage) - Starts nitrous flow at any level you set (from 0-100%) and then gradually brings in the full 100% flow of nitrous over a time period adjustable from 0 to 10 seconds. This allows you to start with a small shot of nitrous power (say 25 to 30%) to minimize wheel spin off the line; then smoothly transition to full nitrous power when the tires can hook up and handle it. ET improvements of up to 1/2 second and more can be achieved with the simple addition of an NOS Progressive Controller. May be used with the most single stage nitrous systems. It features a black anodized, billet aluminum case and unique adjustment knobs that lock into place, so the progressive settings can't accidentally be changed.
