The HKS EVC has improved boost stability for maintaining pressure at high RPMs providing increased top-end power, and a new mapping feature allows boost pressure to be precisely tuned for throttle + RPM (or vehicle speed). The new EVC also offers a selectable kPa or PSI unit of measure, and a unique warning feature where if over boosting occurs, boost pressure can be programmed to drop to a user preset level.
