Audi 3L TFSI engine is one of those rare experiments gone right for Audi. VAG Concern knows the ropes of Turbo set ups and fast NA V8s, so release of Supercharger was slightly unusual. The ‘T’ in ‘TFSI’, “no longer stands for turbo, but rather the concept of supercharging in general.” Figure that one out.
Since the release August 2008, at the Moscow International Motor Show its been installed in almost every Audi model. Grunty, nimble, plenty of potential. A6, A7 SQ5, Q7, S4 and S5 all have them. While gains vary between models and ECU types, let look at one of the more common cars on New Zealand roads. Early version S4.
Stock: 329 HP and and 440 Nm of torque. Enough? No, definitely not. Somebody stole another 80 HP 80 NM torque from you. Culprits are: Tax regulations for power output, Different fuel programmings and Audi still needs to sell RS4 as the fastest A4.
Remap on stock parts and internals gains you solid 80-98hp and 80-97nm of toque. Depends on Fuel and condition of the engine.
