Mate you could amply the throttle signal to 400v and it wont get you any more power.
That thing just adjusts the voltage output of the stock accelerator pedal sensor, such that say a small movement of the accelerator pedal can now cause a larger voltage to be applied to the ECU input and hence cause a larger throttle plate movement for a smaller accelerator pedal input change.
This will certainly give you the impression that the car has more power or acceleration, but the simple fact is its not going to produce any more power or torque than if you just were more aggressive with the standard setup.
The ecu has say a 0 to 5v input and this is interpreted as the accelerator pedal movement say 0v is no throttle and 5v is full throttle. Your device can adjust the rate of change of this voltage, but putting more volts than 5v onto this input of the ECU achieved nothing as the ecu has already interpreted it as 100% throttle application at 5v so feeding 6v or 8v into it achieves nil.
you can achieve the same result by adjusting the throttle tables in the ecu code, but again you produce NO extra power or torque. your just adjusting the "feel" of the throttle pedal to make it more or less aggressive.
for the cost of that device you could likely get a proper ecutek or oft or other tune and actually achieve power and torque increases, by actually changing the ignition timing, fueling, intake and exhaust cam timing.
If you want one of those throttle controllers then buy one but the claims are false and misleading.
