Intelligent Multichannel Petrol & Diesel Tuning Boxes For Your Car, Van Or Motor Home

Easy gains in performance and economy and simple to install and safe

Virtually all of the Petrol and Diesel Performance Systems we supply are "Plug and Play". They are manufactured in Germany using Original Equipment Manufacturers (OEM) connectors matching those used in the vehicle exactly. The Tuning Boxes simply plug in to the vehicles existing plugs to increase the engines performance and economy No wires to cut, simply plug in and drive keeping your vehicles warranty intact.

Once you have bought and fitted your Petrol or Diesel Tuning Box from DTUK you can expect between 20-40% more power and torque. You will also notice that your engine will run with a new smoothness that has to be driven to be believed. Low down "flat spots" will virtually disappear on your vehicle – we tune Cars, Vans, Motorhomes, Tractors, Trucks, Wagons and more - and will pull through the gears with much more ease. You should also see an improvement in your vehicles fuel economy too, usually a 10-15% improvement is achievable as your engines efficiency is optimised.

DTUK Performance Systems sit between the vehicle’s ECU and fuel injection system via the common rail, fuel injectors and other sensors depending on application.

Let’s take a diesel engine as an example of how the tuning box works:-.

In a diesel engine it is only air that is drawn into the compression cylinder, this is then compressed and reaches a very high temperature. When the piston is nearing the end of its cycle fuel is injected into the chamber and ignites due to the high temperature of the air.  This gives the power to drive the piston down. There is extra air left in the cylinder after this process, sometimes as much as 50%.

When extra fuel is injected into the chamber more torque and power and is created. The DTUK Tuning Box injects the optimum amount of fuel into each cylinder that results in the engine running more efficiently, and in most cases fuel economy is improved. This is due to the fact that you do not need to use as much throttle to propel your vehicle due to the increased power and torque.
