PedalBox & PedalBox Pro – Sharper Throttle Response

Many modern vehicles suffer from noticeable throttle lag caused by the electronic accelerator pedal (drive-by-wire). Our PedalBox range completely transforms this.

These plug & play throttle response controllers remove the delay between pressing the accelerator and the engine reacting, giving you a much more immediate, sporty and enjoyable driving experience.

PedalBox (Standard)

  • Dramatically improved throttle response
  • Multiple driving modes (City, Sport, Sport+ and more)
  • Ideal for petrol, diesel and hybrid vehicles
  • Simple DIY installation in minutes
  • Fully reversible with no permanent changes

PedalBox Pro – The Latest Version

  • All the benefits of the standard PedalBox
  • Wireless remote control
  • Smartphone app control
  • 5 driving modes including Eco mode
  • Fine adjustment on every mode
  • Immobiliser function for extra anti-theft protection
  • Limit Mode – restrict throttle response for valet or learner drivers
  • Available for petrol, diesel, hybrid and electric vehicles

Note for Electric Vehicle owners: When you select the PedalBox Pro for an EV, you will receive the PedalBox EV version, which is specifically optimised for electric vehicles.

Both versions work perfectly on their own or alongside a DTUK tuning box. Many customers choose the combination of a tuning box + PedalBox Pro for the ultimate upgrade in power and response.

Electric Vehicles (EVs) – What We Can Offer

Many customers moving from petrol or diesel cars to an electric vehicle ask about tuning for more power and torque. Unfortunately, pure electric vehicles cannot be tuned in the same way as traditional combustion engines.

There is no fuel system, boost pressure or injectors for a conventional tuning box to modify. As a result, we do not offer power-increasing tuning boxes for pure EVs.

However, we can still significantly improve the driving experience with the PedalBox EV.

The PedalBox EV is a dedicated plug & play throttle response controller developed specifically for electric vehicles. It offers:

  • Much sharper and more immediate throttle response
  • Up to 20% less energy consumption during acceleration phases
  • Potential for increased range and lower charging costs per km
  • Special Long Range mode designed to improve efficiency
  • 5 driving modes (including Long Range, Comfort, Dynamic and Performance) with fine adjustment on each
  • Wireless remote control and smartphone app
  • Immobiliser function for extra anti-theft protection
  • Limit Mode (useful for valet parking or learner drivers)
  • Simple DIY installation and fully reversible

When you order the PedalBox Pro for an electric vehicle on our website, you will automatically receive the PedalBox EV version optimised for your EV.
