Overview

The Alky Control GM Truck MAP Kit is a nitrous oxide system designed for 1999-2007 GM trucks that utilize the washer tank. It includes a modified GM washer bottle and features a 2-bar trigger, with an optional 2.5-bar MAP sensor for applications exceeding 15 psi of boost.

Show original supplier description

The Alky Control GM Truck MAP Kit is engineered for 1999-2007 GM trucks, integrating seamlessly with the existing washer tank system. This kit includes a new GM washer bottle that has been pre-modified for easy installation. It comes standard with a 2-bar trigger, suitable for smaller turbochargers or centrifugal blowers. For vehicles operating beyond 15 psi of boost, a 2.5-bar MAP sensor option is available to precisely monitor boost pressure. Installation considerations vary slightly based on the truck's model year. For 1999-2002 trucks, the original float switch is different, and a new float switch for the tank will need to be purchased separately. For 2002 and newer models, the original float switch can be reused. Base model Silverado trucks may not have come with a factory float switch, so checking for a wiring plug on the side of the tank is recommended, and the float switch may need to be purchased separately. Mounting options are also addressed: a vertical panel is offered for 2WD trucks where the dash cubby slot between the gauge cluster and driver's side AC vent is open. Conversely, 4WD trucks typically have controls in this slot, making the horizontal version the preferred choice.
