The new and updated dual-stage boost controller now features a billet aluminium housing and bullet valve technology for ultra-fast boost response with two adjustable boost levels. Toggle between high and low boost on the fly. Ideal replacement for factory boost controllers. Both high and low boost settings are fully adjustable. All Turbosmart Gated Boost Controllers feature our exclusive Gate feature, which minimizes wastegate creep and can improve turbo response by up to 800 rpm earlier in the rev range – this means you can increase the performance and response from your engine without even raising the maximum boost level. Stable increases in boost over wastegate spring pressure of 200%+ for internal and 100% for external wastegates are standard practices using our manual boost controllers. They are manufactured from high-grade billet aluminium and are renowned for their easy installation, robust design, and stability. Our detent adjustment system allows for accurate and simple tuning of boost pressure. The Turbosmart Gated Boost Control Valve range is ideal for mildly modified turbocharged engines and is perfect for increasing boost levels on factory turbo cars and engines.
