Boost Controller

The Boost Leash is a 5 stage time based plus launch stage Race/Street style boost controller.  This unit is very accurate and consistent. Now since it's a gate pressure controller you have to understand that the numbers you set in the controller ARE NOT boost. It's gate pressure. Let me explain what it does. So you have wastegates to control boost and it's normally set by a spring in the wastegate that gives you X amount of boost. Well what this controller does is gives you a imaginary variable spring . You start out by putting at least a 3-5psi spring if you're running co2 or compressed air. If you're running manifold pressure you will need to run a spring that's half what your max boost will be. And the way this controller works is that you set gate pressure curves and these curve are pressure that's applied to the same area in the wastegate as the springs are in. Your programmed gate pressure curve does the same thing as the springs do only you can vary it with the pressure curves.
