Ditto, something is wrong there. I watched those videos and wondered where was the WOT part. At WOT the truck and the engine should be very noticeably trying hard.
I had a policeman stop me once because he heard me go by, right past a red light, where I had floored it up until I hit 2nd gear. I wasn't speeding excessively at 2nd gear, but he figured I was going to go a lot farther at WOT. I was turning at the next block, going to work. I was simply enjoying the sound of WOT for a short bit.
Those video clips sound more like normal driving for my trucks, just mild throttle.
