Subaru SVX 100 to 120 kmph performance after 22 years. No special modif

My 1994 Subaru SVX in a regular acceleration from 100 to 120 kmph. Notice that the POWER option did not activate, this means that the press on the accelerator pedal was not sudden but progressive and smooth. If the press on the accelerator pedal is fast, then the POWER mode is automatically activated and trasnmission kick down to 2nd shift, this recovers speed maybe twice as fast as what you see here. The engine is an all stock 22 years old EG33, 3.3liters, H6, 24 valves, Ferrary intake manifold system with independent bank injection compute management.
