Chip Tuning, Rs2 Stage 1+, Aan/Aby/Adu



SKU: 034-103-2002

Manufacturer: 034Motorsport

034Motorsport is proud to offer 034EFI Chip Tuning for the AAN/ABY/ADU I5 20VT. Countless hours of dyno, street, and track testing go into each of our 034EFI tunes before release, to ensure an unparalleled driving experience.

The 034EFI RS2 Stage 1+ Chip Tune was developed to be the ultimate chip tuning solution for C4 Audi S4 & S6 (UrS4/UrS6) vehicles that have upgraded to an RS2 turbocharger. This chipset remaps the factory ECU's boost, timing and fueling to match the larger RS2 turbo, providing increased power without sacrificing reliability. The RS2 turbo offers a broad powerband with massive low-end torque, and impressive top-end horsepower.

This tune is recommended for all AAN engines equipped with an RS2 turbo, and utilizes the stock fuel pressure regulator (FPR) and mass airflow sensor (MAF). Does not require upgraded rods or pistons.

  • Dyno Proven 285 WHP & 335 WTQ (Gains of 100 WHP & 140 WTQ Over Stock AAN)
