I find that under hard acceleration that sometimes my car almost has a delay shifting from first to second. All of my other shifts are seamless regardless of how many more gears I go through.
This really got my attention a few days ago when it shifted from first to second and caused wheel chirp which I know is common in any standard but I have not come across it in this car.
BTW This is my first automatic ever.
Thanks!

What mode are you in? Put it in S mode and it should have quicker shifts. The car starts off in comfort mode so put it into S or S+
Also in regards to wheel chirp your driving a car with 451hp and 443lb-ft of torque...wheel chirp is inevitable. Maybe invest in some wider tires, especially if you are running 255's in the rear.
Finally, if you don't like the "sluggishness" of the tranny get it tuned by a reputable tuner and they can make the shifts more crisp.
