Innovate PSB-1 PowerSafe Boost and Air / Fuel Gauge Kit | 3892

The Innovate PSB-1 PowerSafe is an all-in-one performance gauge that combines wideband air/fuel ratio monitoring with boost tracking and integrated safety control. Built around Innovate’s DirectDigital™ wideband technology, it provides real-time AFR and manifold pressure data while actively protecting the engine through programmable safety interventions.

Unlike standard boost or AFR gauges, the PSB-1 adds an intelligent fail-safe layer that can intervene when unsafe conditions are detected, helping protect high-boost and nitrous-equipped engines under load.

Performance Benefits

The PSB-1 is designed for high-performance and forced-induction applications where safety and tuning precision matter. By combining AFR monitoring with boost control logic, it helps prevent lean conditions, overboost scenarios, and unsafe operating conditions in real time—making it ideal for turbocharged, supercharged, and nitrous-equipped builds.
