Are you looking to tune your Vauxhall? If so, you are in the right place!

The DTUK Performance range of plug & play tuning systems and designed to get the most from your Vauxhall. Our systems benefit from the latest in multi-sensor technology and user-selectable multi-map tuning solutions.

Your turbocharged petrol, diesel or hybrid-engined Vauxhall is in the safest of hands. Our market-leading systems are programmed specifically for your vehicle and can be installed at home, usually in 20 minutes or less thanks to our OEM connectors and detailed colour installation instructions.

Our performance systems work in conjunction with your vehicles ECU, which means that all manufacturer safety parameters remain in place.

PedalBox & PedalBox Pro for Vauxhall

Want even sharper throttle response? Add a DTUK PedalBox or the advanced PedalBox Pro. These plug-and-play throttle controllers remove the “laggy” feel of modern drive-by-wire systems, giving you instant, more responsive acceleration. Perfect for both daily driving and more spirited use.

• Multiple driving modes (Eco, Sport, Race, etc.)
• App control on PedalBox Pro
• Fully adjustable and reversible
• Compatible with petrol, diesel, hybrid and electric Vauxhalls

Electric Vauxhalls (EVs)

Modern pure electric Vauxhalls (such as the Corsa Electric, Mokka Electric, Mokka GSE, Astra Electric, Grandland Electric and Frontera Electric) cannot be tuned in the same way as petrol or diesel engines because there is no traditional combustion engine or ECU fuel/boost mapping to modify.

However, we can still improve the driving experience significantly with the PedalBox EV. When you order the PedalBox Pro for an electric Vauxhall on our website, you will automatically receive the PedalBox EV version. Benefits include:

• Much sharper throttle response
• Reduced lag from the electronic accelerator
• Multiple driving modes for everyday or performance use
• Immobiliser function and Limit Mode
• Simple DIY fit and fully reversible

Once the system is installed you will immediately feel the increased power and torque that your engine has to offer, alongside improved throttle response and optimised driveability taking your Vauxhall to a whole new level of performance.

By transforming the torque and power on offer throughout the rev range you will find that your vehicle can more easily attain and maintain speed whilst also being able to drive smoothly in higher gears earlier and for longer helping you to increase economy. Many competitors look purely for the maximum power but that is rarely the optimal way to tune a vehicle. At DTUK we aim to ensure a vehicles drivability is maintained or enhanced so that power feels strong, linear and ‘factory’ in the way it is delivered.

We love to hear from our customers so if you have any pre-purchase questions please don’t hesitate to contact us.
