Upgrading to a larger turbocharger is one of the most effective ways to unlock substantial horsepower gains, but it introduces significant challenges for your engine management system. When your build is calibrated to exceed 29 PSI (2.0 Bar) of manifold relative pressure—commonly referred to as boost—your factory-installed sensors quickly become the weakest link in the chain. The stock units are simply not engineered to read beyond their narrow pressure ranges, which forces your Engine Control Unit (ECU) to rely on inaccurate or “clipped” data. This lack of precision can lead to dangerous lean fuel conditions, unpredictable timing adjustments, and catastrophic engine failure under heavy load.

To safely harness the potential of your high-performance turbo setup, upgrading your Temperature Manifold Absolute Pressure (TMAP) and Post Upstream Throttle (PUT) sensors is absolutely critical. These components work in tandem to provide the ECU with accurate, real-time pressure and temperature readings. With precise data, your tuner can build safe, aggressive fuel maps that maximise power without compromising engine reliability.

We are proud to offer the ON Performance 5 Bar Sensor Kit—a comprehensive, plug-and-play solution engineered specifically for high-boost applications. We have eliminated the headaches typically associated with sensor upgrades by designing our components for a seamless, hassle-free installation.

ON Performance 5 Bar TMAP Sensor: This high-precision sensor installs directly into the factory location on your intake manifold without requiring any permanent modifications. It utilises the stock OEM connector, meaning you can say goodbye to custom wiring, bulky adapter harnesses, or complicated splicing.

ON Performance 5 Bar PUT Sensor: Equally important, this sensor integrates flawlessly into your existing stock or aftermarket throttle pipe. The straightforward mounting process ensures a clean, professional install that gets your vehicle back on the road in record time.

Don’t let outdated sensors sabotage your expensive turbocharger upgrade. Choose the ON Performance 5 Bar Kit for uncompromising accuracy, durability, and peace of mind.
