Commonly used with MOTIV ReFlex or CANBOXPRO systems to control externally gated turbo setups on B48, B58, and S58 engines.
If you're running an external gated turbo setup on your B48, B58 or S58, you'll need a boost controller that can handle the job. That's where our 3 Port MAC Valve Boost Controller comes in.
This plug and play solution is designed for easy installation and seamless integration with a MOTIC ReFlex or CANBOXPRO unit, giving you complete control over your boost levels. The harness has a full-length anti-chafing sleeve to ensure longevity and durability, and the wire length is extended to accommodate multiple mounting locations.
This comes with custom Visconti Tuning fittings which allow the T fittings to go deep into your vacuum line and allow a wide enough gap to use a zip tire without damaging the line. The fitting threads are also adjusted to they have a more natural flush look.
