I picked up a 17 Yukon Denali with adjustable pedals a couple months ago. I thought the light throttle acceleration was "soft" and vague. An example of this is when i back it into the driveway. It is a very short drive, not too much bigger than the truck itself and it is pitched forward. I am backing up a very short hill. Having the vagueness in the pedal made it a bit interesting trying not to put the truck through the tiny garage door. I ran across this thread and thought that what is described here sounded a helluva lot like what i felt, and not just while backing into driveway. Did a bit of showing off with a brake torque and I could really feel the vibration, in the entire assembly, as you have a foot on each pedal. So I cut a paint stir stick up and put a double thick piece in behind at the corner as there was a lot of flex in mine. Much better now. It is not like there is ~more~ power, it is the way it comes on. What i would call proper, with feedback. This difference is felt on all of our off idle acceleration conditions we face in our daily drives. Lay off the pedal in busy conditions and get back on it, the vague "lag" as you depress the pedal is near completely gone. The one really nice change with this repair is with the 1-2 shift. Quite a bit quicker now. I like this. Under light acceleration it did feel like granny double clutching her old Studebaker, took forever and felt very weak. Not any longer. As a whole, much better drivability with this mod, errr repair. Thanks OP! Dale
