Subaru WRX 2.5 STi 300hp Stage1 Tuning File
We ensure that the 300 hp / 407 nm torque engine power produced by your Subaru WRX 2015 - 2017 model vehicle with the standard option software reaches 330 hp / 467 nm torque after the application of the customized Subaru WRX 2015 - 2017 vehicle software (Subaru WRX 2015 - 2017 Chip Tuning). After the +30 hp / +60 nm torque power increase, your vehicle's exhaust emission values do not change and do not smoke.
We enable you to use it safely by revealing the power that the factory has restricted due to parameters such as taxation system, sales policy and fuel quality, with licensed software. As a result of this process, there is no harm as the limits set by the factory are not exceeded.
The chip tuning software process to be applied to the engine of your Subaru WRX 2015 - 2017 vehicle takes an average of 1-2 hours, please contact us for more information.
