As easy to use as a manual boost controller, but with advanced electronic boost controller response & consistency, the PRofec Type-S keeps things simple. Based on the ever-popular Original PRofec B-Spec, the Type-S has two rotary switches to select two independent boost setting (a Lo. and a Hi.), while another "Gain" switch compensates the wastegate’s valve response. Now, matched with a quick acting, large capacity inline control solenoid, the Type-S can increase boost as high as 3.0kg/cm2 (42.66psi) and it works with both integral and external wastegate set-ups, while still being compatible with our Remote Switching System or SCC & adapter.
