Agreed, these turbo engines respond differently than a NA engine. Even at high RPM's it's shift, wait a hair, and then go. Definitely needs some planning instead of instantly going.

Throttle response on some GM engines isn't all it could be from the factory. Even my old 3800 Series II (L36) Buick had an awful lag before it would kick down and go. A tune took care of that, and made the car drive "like it should". Nothing like mashing the gas at 35 mph, as it would do a 3-1 downshift and rocket forward.

I checked my spark plug gaps and got the following:
.022
.025
.024
.019

I changed gap to .035 and the crazy idle is completely gone.Throttle response is slightly better. Thank everyone for the post. I really think Chevrolet goofed on this one. I'm going to fill up and check gas mileage and post results later. AWESOME!!!

I'll tell you right now that the .019 plug was the biggest cause of your issues. Good work! You can finally enjoy your car!

I found my plugs were between .021 and .024
Since the factory recommendation is .028, I changed all mine to .032 (split the difference with .028 and .035)
It noticed an immediate improvement in the idle. The acceleration was better as well and didn`t seem to need to shift down or gun it to get going.
I suspect my mpg will improve with this 15 minute adjustment too. (I didn`t realize hoe easy it was to remove the plugs on this engine!)

Thanks for the tip!

I just purchased a 2011 Chevy Cruze LTZ RS. I've noticed that on take off the car hesitates a second before it goes. Example: pulling into traffic is very dangerous because when I floor it the hesitation sucks. Is anyone else having this issue?
I have the similar problem
