I orginally posted on what a bad surge I had when pulling my 40' GN empty. Boost would sore, and throttle would damn near hit the floor. This is with a stock transmission. Now I have done some driving with my Full DTT and the surge is gone. I am guessing the power going into the stock transmission was getting lost, and the truck was not accelerating quick enough, thus the full throttle. Now I get a very small surge when engaging OD while pulling my trailer empty.
