CPA Chiptuning through our CPA PowerBox, easy plug & play power module solution, uses hidden factory power reserves in your engine. With CPA PowerBox chip, your engine develops noticeably more power without increased wear.



The CPA PedalBox significantly improves the throttle response of your vehicle. Depending on the setting of the PedalBox different characteristics are possible. The setting can be easily adapted to the respective driving situation via the buttons.



The CPA Connective system has a patented communication solution between PedalBox and PowerBox in the engine compartment. If the setting of the PedalBox is changed, the characteristics of the PowerBox are automatically adjusted.



Another innovation from CPA Chip tuning is the patented connectivity system.

The driver benefits from the optimal and interconnected interaction between CPA PedalBox and CPA PowerBox.

The power delivery is increased as is the response control of the accelerator pedal, on demand.

Enjoy up to 31%* more power and up to 70% more response from your standard car.

Aluminum casing

For our PowerBoxes we use aluminum enclosures to protect the high-quality electronics against external influences such as water or heat.

Modern electronics

Our PowerBoxes use modern, high-quality electronics, so that characteristic curves in the nanosecond range can be adapted to the respective situation.



To our news


Our four-wheel dyno

We dyno cars with front-wheel drive, rear-wheel drive and all-wheel drive up to 1,100 Nm of torque. CPA’s measurable results!

At our tests, we always rely on extensive dyno tests including exhaust gas measurement and testing of the working temperatures of various engine parts. We use a set of external temperature sensors, which check and record the important operating temperatures of various engine parts with and without tuning. With new engines, intensive tests are always carried out at full load and with maximum power increase.

For many years, we, the management and development team of CPA, have been developing and designing a variety of software and technical products. Now we have packed all this know-how and all our experiences into the PowerBox and PedalBox. We do not leave anything to chance.

We rely on experienced and award-winning engineers from the Stuttgart area.


Power increase and environmental protection are no longer necessarily in conflict with chiptuning of CPA Performance. When the torque is increased during power optimization, more efficient use of the turbocharger can be achieved with higher boost at lower rpm. This in part, leads to more fuel saving, particularly when towing or cruising.


Not only our development team, but also our management has many years of direct racing experience.

At CPA Chiptuning we strive for extraordinary performance! This is both a requirement and a motivation – for our company and our products. The management and development team at CPA Chiptuning can look back on more than 40 years of racing experience in motorsport. These included Formula 2 (EC), World Championship races in motorcycle racing, go-kart racing, Supermoto and most recently the national Superbike class. This racing experience is combined with detailed engineering work from the automotive region of Stuttgart. Every day we work passionately to strive for excellence. That is how our PowerBox came into being, into which we put all our heart and our expertise. See for yourself.

Our CPA PowerBox | Our CPA PedalBox | Our CPA Connective System – Our Vision

CPA Commitment

Our motivation and inspiration behind making of the CPA Chiptuning, is to become technical leaders and to specialise in automotive chip tuning (TuningBox, PowerBox).

The management and the technical development team at CPA Chiptuning can look back on more than 40 years of automotive engineering and racing experience. Racing experiences include Formula 2 (EC), World Championship races in motorcycle racing, go-kart racing, Supermoto and most recently the national Superbike class. Out tuning experience derives from racing and combines high degree of  detail in engineering and electronic work from the automotive region of Stuttgart, Germany.

This makes our tuning box (plug and play ECU power tuning system) an extremely easy to use and effective chip tuning solution (CPA PowerBox). Through our commitment to a modern approach, a chip tuning solution created within our CPA PowerBox was born. The extra power with our PowerBox (TuningBox) is always noticeable, and the throttle response is also vastly improved, particularly when combined with our CPA PedalBox system. We rely on quality directly from the heart of the best regional electronic componentry manufacturers, that is why our products are designed, developed and manufactured directly with us in Germany. Our PowerBox’s use modern, top of the range processors. These allow fast characteristic optimization on the fly, with instant input and response where required. The management and development team of CPA Chiptuning has been developing software for many years.

All our experience and knowledge we pack in our tuning box to be able to offer all of the development improvements in both the hardware and software componentry alike. We deliver your CPA Chiptuning PowerBox with a software especially designed and tuned for your vehicle engine type. This corresponds to our standard and basic setting when delivered straight out of our factory. However, you have the opportunity to adjust our PowerBox according to your wishes individually and very conveniently to maximise your driving experience. The combination of up to 72Mhz (Nitro only) fast processors and sophisticated software, you get the ultimate upgrade package for your increased power, response and economy in everyday driving.

Quality Hardware

Externally, our tuning box differs vastly from our competitors. No cheap plastics with fancy design and gimmicks and no opportunity for moisture entering the sensitive electronics. For CPA PowerBox, we use expensive aluminium case protected by a high heat resistant and industrial grade coating. Our PowerBox case is equipped with a special soft plastic seal and a specially CAD developed and waterproof connectors, unique in our field. This way, the PowerBox interior can be protected from moisture and dirt. The degree of protection is rated at IP 67, which corresponds to a comparatively high standard in the industry. For our connectors, we decided to develop our own, so that we can be confident that the data signals are transferred quickly, efficiently and securely. With the radio remote control, you can activate and deactivate our top CPA Connective model from the vehicle interior. The PowerBox delivers maximum power at the push of a button. With our products, fuel consumption and added performance are no longer in conflict.

  • CPA Pedal Box

A low cost, self-install, no-brainer accelerator lag fix solution for any car, whether turbo or non-turbocharged, petrol or diesel. In modern vehicle, the fly by wire setup caused immense delays and, on some vehicles, frustrating delay condition when trying to accelerate rapidly during an overtake or in a traffic situation. Many owners (particularly on turbo vehicles) complain about the accelerator lag and the delay between the pressing of the accelerator and the actual vehicle moving as required. The CPA Pedal Box fixes this condition by providing you, the driver with the exact control over the accelerator behaviour. Learn More.
