As with all major developments at PERON Automotive, our EA855 EVO calibration is the culmination of months of dedicated work by highly experienced engineers in our world-class facility. Despite our extensive time spent on the earlier CEPA/CZGB engine over the years, we approached the EA855 EVO and its new mixed injection with a clean sheet. Months of in-depth research and development with the Bosch MED17.1.62 ECU allowed us to fine-tune the engine’s behaviour to perfection. The results speak for themselves—not only in raw performance metrics but also in the enhanced driveability that transforms every driving experience.
This Performance Software Package Includes:
-
PERON Tuning Stage 2 ECU Tune: Developed by NickK, PERON's head of engineering, this tune optimises throttle response, power delivery, and torque for enhanced performance and sharper acceleration. Calibrated with precision, it delivers smoother power distribution while ensuring the engine operates reliably under increased load.
-
TVS Engineering Stage 2+ TCU/DSG Tune: TVS optimises shift logic, increasing shift speed, clutch pressure, and torque capacity, while also improving thermal management and launch control. These calibrations deliver refined yet dynamic shifting for the DQ500 gearbox.
These tunes were developed to work in perfect synergy, delivering exceptional performance and driveability for your Audi TT RS 8S.

PERON Tuning Stage 2 ECU Tune for the Audi TTRS 8S
Enhanced Driveability and Performance
Designed to increase engine output to between 475-500 horsepower and 475-525 ft-lbs of torque, the Stage 2 takes advantage of the EA855 EVO's inherent potency. The engine is so good that careless tuning can easily exceed the capabilities of the connecting rods. Because of this, careful consideration was given to safety and long term reliability, which is why the engine torque has been left at a conservative level. The primary goal is to refine power delivery, enhancing the response and smoothness of acceleration while improving on the already excellent driveability.
Fuel Requirements and Efficiency
The Stage 2 calibration is optimised for 99 RON fuel. 97-98 RON can be used but will reduce performance and efficiency. By optimising fuel usage, this stage ensures that the engine operates efficiently, making the most of the increased power while maintaining the car's fuel economy.
Hardware Requirements
-
NGK Competition R7438-9 Spark Plugs
-
High-Flow Air Intake
-
Large-Bore Downpipe (76-100mm) with high-flow catalyst
