Bought earlier in the year, this was fitted to A4 3.0 TDI 233bhp should be ok on with all VAG 3.0 TDI engines. Takes power from 233 BHP to 301 BHP and torque goes from 450nm to 541nm with a slight improvement in MPG.
The box is German made quality and from a reputable company. These are not just a resistor in a box, they have a 24mhz processor.
Will turn up in the original box and with all the instructions. 5 minutes to fit and you will feel the difference. Box is tune able so you can have a play around to see what suits you best. Still under manufactures warranty
