- Porsche 911 1987-1989 3.2L G50
OE Match 24-Pin Performance Upgrade Chip – USA/Canada Specification – Premuffler / Cat Bypass Configuration
Transform the performance of your 1987 USA/Canada specification Porsche 911 Carrera 3.2 with the OE Match 24-Pin Performance Upgrade Chip, specifically developed for 930/21 and 930/25 catalyst engines fitted with a premuffler or catalytic converter bypass pipe, while retaining either the factory rear silencer or a sports muffler.
Fits:
- Porsche 911 1987 3.2L G50
Replacing the restrictive catalytic converter allows the 3.2-litre flat-six to breathe more efficiently, but without optimising the Bosch Motronic ECU, much of the potential performance gain is left untapped. This OE Match calibration has been developed specifically for freer-flowing exhaust systems, delivering stronger torque, sharper throttle response and smoother power delivery throughout the rev range.
Planning your exhaust upgrade? This chip can be installed now on a standard catalyst-equipped car, allowing you to enjoy its drivability improvements immediately before fitting a premuffler or cat bypass at a later date.
Developed for Real-World Performance
Unlike generic replacement chips, every OE Match Performance Chip has been developed from a completely new calibration. Hundreds of hours of software development, road evaluation and dyno testing across more than one hundred Carrera 3.2 models have produced a calibration that transforms the way the car 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 during deceleration
- Reduced overrun backfiring
- Strong pulling power from just 1,500 rpm
- Dyno-proven horsepower and torque gains throughout the rev range
The result is a Carrera that feels noticeably lighter, more responsive and considerably more enjoyable to drive. Many owners describe the improvement as feeling like the car has shed 500-600 pounds in weight.
Many customers also report 10-15% improvements in highway fuel economy, thanks to improved part-throttle efficiency.
1987 Model Year – 24-Pin or 28-Pin?
1987 was a transition year, with Porsche changing from a 24-pin EPROM to a 28-pin version during production.
The only reliable way to determine which chip your vehicle requires is to remove the DME control unit and count the number of pins on the original EPROM. The factory chip is a black rectangular unit fitted with a silver foil label displaying a number similar to 1267355xxx.
If your DME contains a 24-pin EPROM, this is the correct OE Match Performance Chip. If your vehicle has a 28-pin chip, please select the dedicated OE Match 28-pin version.
Why Choose OE Match?
This is not a "one-size-fits-all" performance chip. OE Match calibrations are engineered specifically for individual Porsche engine and exhaust configurations, ensuring the Bosch Motronic system delivers maximum performance while maintaining smooth drivability and factory-level reliability.
Benefits
- Increased horsepower and torque
- Sharper throttle response
- Eliminates the factory low-RPM hesitation
- Improved acceleration throughout the rev range
- Smoother idle and reduced deceleration backfiring
- Better everyday drivability
- Potential improvements in fuel economy
- Maximises the benefits of a premuffler or cat bypass exhaust
Porsche 911 Carrera 3.2 Premuffler & Cat Bypass Performance Chips
A premuffler or catalytic converter bypass is one of the most popular upgrades for the Porsche 911 3.2 Carrera, improving exhaust flow and allowing the flat-six engine to perform more efficiently. However, to unlock the full benefit of these modifications, the Bosch Motronic engine management should be recalibrated to match the improved exhaust characteristics.
OE Match Performance Chips are developed specifically for USA and Canada specification Carrera models, with calibrations tailored to standard, premuffler and cat bypass exhaust configurations. Every chip is designed to improve torque, throttle response, drivability and overall engine performance while maintaining the reliability expected from an air-cooled Porsche.
