I still can't believe they have so many GM "Performance" parts that obviously require a different calibration, and how do they expect anyone to get a non stock calibration? haha

As far as the BIG 3 go, Dodge is the easiest, then Ford, heck they offer tons of warranty compliant tuning options off the shelf.. Gm is tight on every code and calibration, making even a simple CAI's require PCM modification.
But, don't let that get ya down.
On my 18LTG, I am using a completely UN-detectable, by any tool we use here at the dealership level, EFILive tune. I have personally tried to detect incremental PCM write counts UN-sucessfully.
