Incorrect wastegate plumbing, solenoid configuration, targets, or fail-safe settings can cause uncontrolled boost and severe engine damage. Testing must begin at minimum mechanical boost and proceed in controlled increments while monitoring fuel pressure, air\/fuel ratio, and all engine-protection channels.\u003c\/p\u003e\u003cp\u003eDown Dirty 84 LLC is an independent calibration provider and is not affiliated with or endorsed by Holley Performance Products.
