The 2015 to 2017 RS3 8V makes 367hp and 465Nm from its five-cylinder 2.5 TFSI. Our Stage 1 calibration takes it to around 420hp and 620Nm on 99 octane fuel, with the torque limiter raised and boost, ignition and fuelling recalibrated. The car is programmed through the OBD port and proven on our 4WD linked dyno; where a customer prefers not to alter the ECU we can fit a plug-in tuning module instead. Exhaust systems are supplied and fitted alongside.
Questions we get asked
Should I choose the ECU remap or the plug-in module?
The remap gives the most complete result because every map in the ECU can be revised. The module sits between the sensors and the ECU and raises boost, so it gives a solid gain and can be removed. We will talk through which suits you.
Is the 8V RS3 gearbox tuned as well?
The S tronic gearbox can be recalibrated for faster shifts and higher torque limits, and we recommend it once the engine is producing 600Nm or more so the box is not holding the engine back.
Does the RS3 need an intercooler for Stage 1?
Not for Stage 1. Intake temperatures do rise with boost, and if you drive the car hard or plan to go further an uprated intercooler is the first hardware upgrade we would suggest.
