Turbosmart TS-0105-1101 GBCV Dual Stage Boost Controller V2 Blue Universal Kit

Vehicle Fitment

• Universal - Compatible with all turbocharged vehicles using boost-based internal or external mechanical wastegate actuator systems

Fitment Notes

• Compatible with both internal wastegate actuator and external wastegate systems.
• Suitable for mildly modified turbocharged engines and factory turbo vehicles with mechanical boost reference circuits.
• Not intended for use with electronic boost control solenoids or electronic wastegate actuator systems.
• Supersedes previous part number TS-0105-1001.
• Rocket Launcher switch requires basic wiring to a switched 12V source for in-cabin or remote boost switching operation.

Features

• Dual stage design allows two fully independent, adjustable boost levels - toggle between low and high boost on the fly via the included Rocket Launcher switch.
• Bullet valve technology delivers ultra-fast boost response for aggressive, on-demand power delivery.
• Exclusive Gate Feature minimizes wastegate creep and improves turbo response by up to 800 RPM earlier in the rev range - without requiring a higher maximum boost level.
• Proven detent adjustment system enables accurate, repeatable boost tuning in defined steps for both high and low boost settings.
• Capable of stable boost increases of 200%+ over base spring pressure for internal wastegates and 100%+ for external wastegate systems.
• Billet aluminum housing with blue anodized finish for durability, corrosion resistance, and a clean under-hood appearance.

Product Description

The Turbosmart TS-0105-1101 GBCV Dual Stage Boost Controller V2 is an updated manual boost controller designed for turbocharged vehicles running mechanical wastegate systems. Building on the proven Boost Tee platform, the V2 adds dual-stage functionality - two fully independent and adjustable boost levels that can be toggled on the fly using the included Rocket Launcher switch. Whether switching from a conservative street setting to an aggressive track boost level, the transition is instantaneous and controlled entirely by the driver.

The billet aluminum housing and bullet valve technology combine to deliver ultra-fast boost response, while the exclusive Turbosmart Gate Feature actively reduces wastegate creep and pulls boost onset up to 800 RPM earlier in the rev range. Both high and low boost settings are dialed in using the detent adjustment system for accurate, repeatable tuning without guesswork. Compatible with internal and external wastegate setups, this controller is well suited for factory turbo vehicles and mildly modified builds looking for a reliable, straightforward dual-boost solution.
