Fast, smooth and reliable


Intense Research & Development

We’ve been developing and testing PCM for over a year and many tens of thousands of miles now. By using our in-house calibration, PCM is designed to work within the safe limits of the factory ECU, unlocking more horsepower and torque without having to modify the factory calibration.

How does RacingLine PCM Tuning Box for Golf R or Golf GTI drive?


Beautiful Drivability

Our tuning philosophy of smooth drivability, outstanding reliability and longevity follows suit on the PCM. We have spent hours of research, development and testing on various applications to make sure that both power and torque are increased without any adverse effect.


Power Games

Dedicated only to the latest generation of MQB EVO models, the PCM has specific versions suitable for either the 2.0 TSI EA888.4, 2.0 TDI or 2.5 TFSI engines.


Power is increased, with superb drivability, safety and the ability to revert to the factory ECU calibration at any time.

How much power does RacingLine PCM tuning box make?


Power and Torque increases

Of course, it's all about performance. PCM will boost your 2.0 TSI by up to 40PS and 60Nm when using our supporting RacingLine hardware versus the quoted factory power outputs, a difference that you'll feel instantly.

Our careful calibration development also means that you don't have to choose between better performance or better fuel economy. PCM's efficiency improvements lets you have both.

How does PCM work?

PCM works by using our in-house developed calibration running on our standalone PCB, which communicates in parallel with the factory ECU.


This communication route allows the PCM to safely optimise a variety of electronic sensor signals in real time, interfacing between the engine controls and its sensors. With multiple channels such as charge air pressure, ignition and fuelling controlled by the PCM computer, the result is increased power and torque across the whole powerband of the engine.

We have carried tens of thousands of development miles of rigorous testing on our in-house dyno, on road and on track with numerous calibrations, across multiple cars and different hardware installations, allowing us to find the sweet spot for engine performance, drivability and safety.

Is RacingLine PCM Tuning Box safe for my engine?



Every product that carries the RacingLine logo has been thoroughly track-tested. And PCM is no exception. 

Why? Because only in hard track-use can we push the car's engine to the limits, again and again. It's reassuring to know that we've done the hard work so you can get on with enjoying your car!


Hardware Compatible 

Right from the outset, PCM has been developed in conjunction with RacingLine's latest Performance Parts for the MQB 'evo' cars. 

Whilst PCM has been developed to work perfectly on an unmodified stock car, it has also been calibrated to self-adapt to take full advantage of any RacingLine upgrades.

So adding the RacingLine R600 EVO intake, plus our new Turbo Inlet Systems will really let the PCM extract the most from your engine.

Can I use air intake and hardware with RacingLine PCM Tuning Box?
What fuel grade can I use with RacingLine PCM Tuning Box?


What fuel grade can I use?

PCM has been designed to work with different fuel grades around the world, just like factory calibration does. Meaning it's perfectly safe, whatever grade fuel you put in your tank.


However, using a lower fuel grade will result in less power, meaning that a premium octane fuel is always advised.


How does it compare to an OEM+ calibration?

We're completely honest about this: the PCM calibration is not as sophisticated as our OEM+ calibrations are.

To keep the car smooth, safe and reliable, PCM's power levels have to be kept lower than we anticipate for our OEM+ Stage 1 calibrations.

But of course, you'll love the power boost you get from PCM, combined with the drivability and efficiency gains. And with our free upgrade program, you can have a free OEM+ calibration as soon as it's available if that's the way you want to go!
