I have had all the updates done and it was the same as you are describing. After finally learning how to drive this beast again (it spent most of its first 700 miles in the ICU), it either just got better or it learned my driving. For me, it just feels like it's smoothly accelerating now instead of the stomp it down power we had with the first gens (I had two). I learned how to feather it a bit and it will take off, just in a more refined way. At first it was strange, but then I got to thinking since I live in an area where it rains so much, this might not be a bad thing. On the first gens, the wheel would spin, tc kicks in, truck bogs, then you had to floor it before the semi plowed into you. On this new one, there is no spin, and no bogging. I think I like that better than the other way. This gets going plenty quick for me. What I do find weird is say, you take a right hand turn, and it is uphill. Then it kicks down before up again. Once you put your foot into it a bit, gets going fine again. Don't know if it is a flaw in the software since my '15 GMC Canyon did the exact same thing, and same results, no wheel spin in the rain, or very little and downshifting before upshifting. What I really would love to drive are the new 10 speed trannies to see how "light" the first 5 or so gears are to have some understanding of anything more than the 5 speeds we are used to from the first gens and compare them to the 7 speed of now. I would think they would even take longer to get going.
