"A much better driving experience with effortless torque and power and improved fuel economy! It doesn't get much better!"


DTA CRD-Flash tuning is THE state of the art way of improving both power and torque for your modern common rail diesel engine. By re-calibrating the factory engine computer unit (ECU) we are able to optimize the engine power and torque output as well as improve the vehicle’s fuel economy by as much as 10%*. Reprogramming the vehicle’s ECU has a number of advantages not at least is that we can retain all of the manufacturers inbuilt safety features as we are not tricking or going behind the ECU’s back. Additionally, reprogramming the ECU gives us the unparalleled ability to alter torque management tables, throttle mapping, boost pressure, fuel pressure & injector timing to name just a few… something no individual chip or module can come close to claiming. Real world average gains of around 25%* more power and 25%* more torque with no degradation to reliability or drivability shows that with CRD-Flash tuning technology you really can have your cake and eat it too!

The process requires the vehicle to be at DTA for a period of one day, where our specialist tuners set the vehicle up on our All Wheel Dyno for a baseline dyno run. The vehicle is then connected to our state of the art ECU reading and writing hardware. Our tuner then continues by adjusting the ECU parameters, all the time monitoring the progress on the dyno screen and via our ECU logging devices and EGT sensors.

After the tuning process each vehicle is returned to the customer along with a dyno graph showing the baseline dyno run and the final run, this graph will display the gains in both Power and Torque for comparison.
