Friday, I was out playing around and hit it hard a few times, it felt like the peddle was suck out from under my foot, but I stayed in it. After words it felt weak and when I stood in it, at hard boost acted as if it wasted to stay there. So keep an eye on your throttle tension spring if you go WFO allot, it has a bad wear point at the bracket. My truck has 8200 miles on it.
