The Stage 1 TCU Software focuses on economy and comfort, by up-shifting early in D-Mode and locking up the torque converter sooner, compared to the factory calibrations. MPG gain to be expected (depending on vehicle and driving environment) between 5% and 15%.
The Stage 2 Software is for people wanting faster shifts and a more responsive driving experience, but not want to sacrifice any comfort.
The Stage 3 Software is our most sporty calibration & a must for all customers looking to completely change the driving experience for the better. While all Stage 3 files retain full comfort and can be used in every daily car, the behaviour changes when switching to S or M. Massively reduced shift times and throttle blips in manual mode show what your auto transmission is capable of. (But never was allowed to do from the factory).
