a little late on the thread but...ok, so it's understood that the ATTSystem will disengage above a certain amount of HP if you were to say, add a turbo/supercharger setup. but how? does the ECU detect the added HP after the motor is dyno'd/tuned and in turn, the ATTS just doesn't activate or...? i know the system uses sensors to detect speed/wheel spin/angle/etc. when in use, but how does it know if you're running boost or not or simply have added more HP?
