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 MOTIV 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.
