Tbh, I never really got why people like it so much. From what I can see, all it does is just change the voltages that is sent to the ECU. So that it's essentially mimicking you pushing the pedal harder. It's more like a SSK for the accelerator pedal, so you don't have to push the pedal down as far to get the same effect. I don't see how it affects throttle response at all. If anything, I feel like it would get marginally worst cause it has to go through the SB now to get to the ECU lol
