I've been meaning to post this query for a long time, finally getting around to it. I owned a 2013 Base Cayenne and the engine was very responsive, traded for a 2017 a while back and whenever I let off the throttle like for coasting around a gentle curve or other traffic maneuvers, and then get back on it there is a lag of what seems an eternity(a couple of seconds at most I guess) before the power comes back on. Its not like turbo lag, and I complained to the dealer about it to no avail. I now have a 2018 loaner and it does exactly the same thing. Is there a fix for this? I am hoping some flash code or other add-on will eliminate this. A couple of times it caused a brief panic when I was facing oncoming traffic and needed to accelerate to get out of the way and was basically a sitting duck until the power came back on.
