Performance Upgrade Chip with Sports Headers and Sports Silencer. Porsche 964 1989-94 › CHIP964HDR8994
- Porsche 964 (911) C2 1989-93
- Porsche 964 (911) C4 1989-93
Performance Upgrade Chip – with Sports Headers and Sport Muffler
Unlock the true performance potential of your 1989-1994
Porsche 964 Carrera 2 or Carrera 4 with the OE Match Performance Upgrade Chip.
Developed specifically for cars fitted with performance headers and a sports
muffler, this calibration is designed for manual and Tiptronic models, with or
without an RS lightweight flywheel, and includes the latest LWF software fix as
standard.
Fits:
- Porsche 964 (911) C2 1989-93
- Porsche 964 (911) C4 1989-93
Designed for Performance Exhaust Systems
Performance headers and sports mufflers significantly
improve exhaust flow, but to extract the maximum benefit the Bosch Motronic ECU
requires recalibration. OE Match software has been specifically developed to
provide the additional fuel and optimised ignition timing needed for
freer-flowing exhaust systems, ensuring safe air-fuel ratios while preventing
excessive knock sensor intervention.
The result is a dramatic improvement in the way your 964
drives, including:
- Increased low and mid-range torque
- Sharper throttle response
- Elimination of the factory flat spot below 4,000 rpm
- Smoother idle
- Dyno-proven horsepower gains
- Improved acceleration and everyday drivability
The engine comes alive from low RPM, making the car feel noticeably lighter and more responsive whether you're driving on the road or attacking your next track day or autocross.
Dyno Developed for Real-World Driving
Unlike generic replacement chips, OE Match calibrations are
written specifically for each engine and exhaust configuration.
Every program has been extensively developed through
hundreds of hours of dyno tuning, road evaluation and real-world testing using
everyday pump fuel. Ignition timing, fuel delivery and throttle mapping have
all been optimised to deliver:
- Smoother idle
- Increased low and mid-range torque
- Sharper throttle response
- Elimination of the factory sub-4,000 rpm flat spot
- Stronger acceleration throughout the rev range
- Dyno-proven horsepower gains
- Improved everyday drivability
Unlike inferior calibrations, OE Match software maintains
safe air-fuel ratios, ensuring the engine continues to run efficiently while
avoiding the lean conditions that can reduce performance and increase knock
sensor activity.
Includes the Lightweight Flywheel (LWF) Fix
Every OE Match calibration includes the latest Lightweight Flywheel Fix, eliminating the stalling and RPM dip commonly associated with RS lightweight flywheel conversions. The software also improves clutch engagement and throttle response while remaining fully compatible with standard flywheel cars.
Developed Specifically for Your 964
Unlike generic replacement chips, every OE Match calibration
has been extensively developed through dyno testing and real-world road
evaluation using premium pump fuel. Each program is tailored to your exact
engine specification and exhaust configuration, delivering maximum performance
without triggering the Check Engine Light.
Suitable for:
- Porsche 964 Carrera 2 & Carrera 4 Manual or Tiptronic transmission
- Performance headers Sports muffler
- Factory or RS lightweight flywheel
Benefits
- Increased horsepower and torque
- Sharper throttle response
- Eliminates the factory sub-4,000 rpm hesitation
- Improved low and mid-range acceleration
- Smoother idle
- Eliminates lightweight flywheel stalling
- Better everyday drivability
- Dyno-developed Bosch Motronic calibration
- Will not trigger the
- Check Engine Light
Porsche 964 Performance Chips for Headers & Sport Mufflers
OE Match Performance Chips are specifically developed for Porsche 964 models equipped with performance headers and sports mufflers. By recalibrating the Bosch Motronic ECU to suit the increased exhaust flow, the engine delivers stronger torque, improved throttle response and greater horsepower while maintaining safe operation and factory reliability.
Design911 offers model-specific OE Match calibrations for manual and Tiptronic 964 models, including vehicles fitted with RS lightweight flywheels. Every calibration is developed to maximise the performance of your exhaust upgrades while preserving excellent drivability.
