Audi S8 4.0l TFSI

The new Audi s8 has Finally got an engine that fits its legend.We consider the 4.0l Tfsi engine one of the best engines that was produced from Audi not only because it is a Biturbo engine producing enormous power in stock levels but also because you can easily gain 100ps with just a software tune.

Audi continues to increase the efficiency of its engines. The new 4.0 TFSI, a powerful V8 with twin turbochargers, is equipped with “cylinder on demand” technology. When operating at part load, four of its cylinders are deactivated.

This reduces fuel consumption by an average of five percent.A close view of the engine bay will reveal the beauty inside the monstrous vehicle.

Cylinder deactivation on the new 4.0 TFSI is activated at low loads, low to moderate engine speeds and in third gear or higher. If these operating characteristics are present, the system closes the inlet and exhaust valves of cylinders 2, 3, 5 and 8.

Efficiency is then higher in the active cylinders because the operating points are displaced towards higher loads. Our software does not interfere with this operation and the full power of the car comes only when you select the sport mode settings.

An enhanced version of the Audi valvelift system closes the valves by means of sliding sleeves on the camshafts.While in s mode car feels and pulls like a monster and using our software we achieved speeds of 320kmh per hour in the German Autobahn.Here is our dynograph.

The fuel is 98 octane in this dynosheet and we consider this tune as stage 1 for a fully stock car. Feel free to ask about any kind of questions you have for this particular tune.
