Greddy Profec B Spec II Boost Controller Silver

The PRofec B-Spec2 integrates all the basics of an electronic boost controller, with additional useful options. Use the built-in boost gauge (psi or kPa) to tune in a Lo. & Hi. SET % to raise the boost pressure, then optimize consistency and response with GAIN % and adjust the START GAIN to set initial wastegate response. Also built-in are optional: Warning point, Warning limiter, and peak & last boost record. Compatible with integral and external wastegates and our RSS or SCC's optional speed trigger.

We have used this on one of our own personal cars and the easy installation and ease of use made it a very nice piece to use
