RACINGLINE OEM+ PERFORMANCE SOFTWARE
Audi RS4 & RS5 B9/9.5
Performance tuning for 2017+ Audi RS4 and RS5 models fitted with the 450 PS DECA 2.9 TFSI twin-turbo V6.
TWO YEARS IN DEVELOPMENT
Beautiful drivability.
Mighty output.
Developed on road, track and dyno, the RacingLine calibration transforms the EA839 while preserving progressive, factory-like response.
Choose Stage 1 with no hardware changes or Stage 2 for eligible non-OPF applications with supporting airflow and catalyst upgrades.
DEVELOPED WORLDWIDE
2.9 V6TT transformed.
Fuel-grade choices, Theft Protect, raised limits, revised temperature management and PDM flash-at-home support are included in the calibration suite.
1
STAGE 1
Stage 1.
A complete transformation.
450 PS · 444 BHP
502 PS · 495 BHP
No mechanical changes are required for the quoted output. TCU software is strongly recommended to unlock the complete calibration and optimise the AL552 transmission.
2
STAGE 2
Stage 2.
Factory-turbo maximum.
450 PS · 444 BHP
531 PS · 524 BHP
Stage 2 requires a cold-air intake, turbo inlet and high-flow catalyst. It is not applicable where the factory OPF/GPF must remain.
