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.

Please select between the two color options, Black or Silver.

Simply put, electronic boost control is where its at, and do not trust the safe control of a soleniod that effects boost pressure to a lesser name than GReddy.
