Knowledge, experience, calibration studies and bench tests are the starting point for the development of the above mentioned bin definition files (xdf).
A free chiptuning software combined with competitive prices (50 euro) are the milestones of our philosophy.
Through the definition files, the remapping software TunerPro identifies the engine working parameters which allow to obtain the maximum power and torque without affecting the degree of reliability.
Please note: the maps listed may not be present in all vehicles because of the different software update and calibration numbers.
