7 Bespoke Programs
We've developed 7 versions of our unique engine map for your exact vehicle to ensure you find the best program to suit your driving style.
Cutting Edge Digital Tuning Technology
The CRTD4 SENT Petrol Tuning Box from TDI Tuning for the Audi RS4 2.9 TFSI Quattro 444 BHP / 450 PS / 331 KW / 600 NM / 443 LBFT is at the cutting edge of digital tuning box technology with the capacity to remap brand new digital sensor based engines from Audi and Porsche. Powered by a powerful 80 MHz ARM microprocessor the CRTD4 remaps vehicle performance moment by moment based on digital data received via the engine sensor interface harness. The engine fuelling profile of the vehicle is then remapped to increase power and torque whilst improving power delivery, eliminating acceleration flat spots in specific gear RPM ranges, and creating a smoother and more responsive drive experience. For your engine, available power will be increased by 62 BHP and available torque will be increased by 72 Nm.
A Revolution In Vehicle Performance Tuning
For domestic vehicle owners the CRTD4 SENT is a flexible tuning solution when compared to traditional ECU Remapping, allowing owners to adjust power and torque output via 7 operating mode settings ranging from maximum economy up to maximum power delivery, ideal for switching between everyday driving and long-haul trips. On top of this the ability to be reprogrammed for over 99% of modern turbo diesel and petrol vehicles, unlike a remap, also represents great value with the cost of a reprogram starting at nearly a ¼ of the cost of a brand new product.
Improved Fuel Efficiency:
TDI-Tuning boxes increase power and fuel efficiency simultaneously using a model variant specific map.
