well, I do have a pedal commander but had a bad experience after the shifter install. I turned it all the way up, entered manual mode and floored it. The truck smoked the tires and launched so hard it caused the tailgate to come down and the hood to fly up. I could not see due to hood being up so I looked out the side window and found I was about 50 feet in the air. The truck had launched like a rocket. I knew the truck was going to be totalled when it hit the ground but, suddenly, the truck began to slowly glide towards the ground. The hood and tailgate were acting like air foils, slowing my decent. I landed gently and immediately turned the pedal commander to its lowest setting. Now the truck is drivable.
