Just to add on to discuss regarding throttle controller. The right one should change the throttle body opening %. By default AKA factory map. Normal opening is 33%. If your throttle controller is changing this opening % then you should feel more gain with Red Bullet as well. As such controller can change the speed of how the throttle body response as well as the % of it's opening. It's not really so much about pedal to the metal being similar.
