OE Match Performance Upgrade Chip – USA/Canada Specification with SSI or Performance Headers

Unlock the full performance potential of your 1984-86 USA/Canada specification Porsche 911 Carrera 3.2 with the OE Match Performance Upgrade Chip, developed specifically for 930/21 and 930/25 catalyst engines converted to SSI heat exchangers or performance headers, while retaining either the factory rear silencer or a sports muffler.

Fits:

• Porsche 911 1984-1986 3.2L

SSI and performance headers significantly improve exhaust gas flow compared with the restrictive factory exhaust system. However, without recalibrating the Bosch Motronic ECU, the engine cannot fully exploit these improvements. This OE Match chip has been specifically developed to optimise ignition timing and fuel delivery for freer-flowing exhaust systems, unlocking additional horsepower, stronger torque and noticeably sharper throttle response.

Developed for Maximum Performance

Unlike generic replacement chips, the OE Match Performance Chip has been developed from the ground up. Hundreds of hours of software development, road testing and dyno evaluation across more than one hundred Carrera 3.2 models have produced a calibration that transforms the way your Porsche drives.

Exclusive OE Match programming delivers:

• Smoother idle with virtually no idle hunting
• Increased low and mid-range torque
• Sharper throttle response
• Elimination of the factory flat spot below 4,000 rpm
• Reduced RPM dipping and deceleration backfiring
• Stronger pulling power from just 1,500 rpm
• Dyno-proven horsepower and torque gains throughout the rev range

The result is a Carrera that feels more responsive and eager, with stronger acceleration across the entire power band. Many owners describe the transformation as making the car feel 500-600 pounds lighter.

Many customers also report 10-15% improvements in highway fuel economy, thanks to more efficient part-throttle mapping.

Designed for SSI & Performance Header Conversions

This calibration has been specifically engineered for:

• 1984-86 USA & Canada specification Porsche 911 Carrera 3.2
• Engine codes 930/21 and 930/25
• SSI heat exchanger conversions
• Performance header exhaust systems
• Standard or sports rear silencers
• Bosch Motronic DME engine management

By matching the ECU calibration to the improved exhaust flow, the engine delivers stronger performance throughout the rev range while maintaining smooth idle quality and excellent everyday drivability.

Why Choose OE Match?

This is not a generic "one-size-fits-all" chip. Every OE Match calibration is tailored to a specific Porsche engine and exhaust configuration, ensuring the Bosch Motronic system is fully optimised for your vehicle.

Developed through extensive research, dyno testing and real-world evaluation, each chip delivers measurable performance improvements while maintaining factory reliability.

Benefits

• Increased horsepower and torque
• Faster throttle response
• Eliminates the factory low-RPM hesitation
• Stronger acceleration throughout the rev range
• Smoother idle quality

Porsche 911 3.2 Carrera Performance Chips for SSI & Performance Headers

Upgrading to SSI heat exchangers or performance headers is one of the most effective ways to improve the breathing of the Porsche 911 3.2 Carrera. To maximise the benefits of these exhaust upgrades, the Bosch Motronic engine management should be recalibrated to suit the increased exhaust flow.

OE Match Performance Chips are specifically developed for USA and Canada specification Carrera models fitted with SSI or performance headers. Each calibration is designed to improve torque, throttle response, drivability and overall engine performance while preserving the reliability and character of Porsche's legendary air-cooled flat-six.
