We are now offering a Stage 1 performance upgrade for the Audi S7 55 TDI Quattro and all other models with a 55 TDI engine. The current version of the 3-liter, six-cylinder diesel engine has a total output of 350 HP and 700 Nm of torque. With our Stage 1 software optimization, the performance of the all-wheel drive from Ingolstadt increases by 50 HP and 100 Nm to a total power of whopping 400 HP and 800 Nm torque. The increase in performance of this model results from the successful optimization of the MD1 control units from Bosch. It is already one of many optimizations of a control unit of this series, and further vehicle models with Bosch MD1 control units will be added in the next few days. You can find more information in our vehicle database.
