Installed mine a couple weeks ago. Maybe 10 minutes total time to install. No battery disconnect no CEL. And a nice noticeable difference in power delivery.
Sorry guys, didn't see the comments before I did it. Literally the easiest install. Use a flathead screwdriver to take off the silver band holding the throttle body. And then a ratchet to remove the 4 screws. I'll try to post a picture tomorrow if I remember.
Also please share cost, supplier, and performance gain you experience. I've been looking at this mod for awhile and must have missed previous posts (if any) on the topic.
Going to do the same mod next week when my aFe CAI comes in, doing both the throttle body & CAI change at the same time. I am using a Weapon X ported throttle body.

BigEasy,
How much is the Weapon X TB? I have the AFE CAI, AR headers and exhaust already and want to do a pulley swap and TB at the same time so we just have to retune it just once.
Thanks

Just to add. Rachet and 10mm socket with extension work fine for the 2 top and lower right bolt, but I had to use a 10mm wrench for the lower left bolt due to clearance issues with the intake tube

??? How does replacing the CAI & throttle body affect the GM warranty ?
As Doug Z06 says, it's a 10 minutes job. I would replace it with my stock tb before going to the dealer. Not sure about the intake but probably replace it too with the factory.
I would think as long as no tune has been installed we should be good on warranty.

Katech Ported Throttle body was 250$ after shipping. I can definitely feel a slightly increased throttle response. It doesn't get 100% get rid of the lag, but it's the best you're going to get without a tune and voiding your warranty. I would recommend it. Cheap mod.
For those interested in seeing the difference between a stock (first photo) and a Katech ported throttle, see below. I highly doubt a ported throttle body would have any affect on warranty. Since it's a 10 minute job you can always swap it out before going to the dealer if you have a concern.
