The variable vane
turbochargers used in diesels today to reduce turbo lag, emissions and
increase power can also be used to slow you down. BD utilizes this technology
by electronically closing off the turbine vanes which can create up to 130
retarding horsepower. This braking force will help to maintain your speeds on
descents and curves, giving you better control of your truck and load. Works
with your cruise control to automatically accelerate and decelerate to
maintain vehicle speed. Easily and simply installs by plugging into existing
factory connectors and by mounting the switch on your dash.
