The tilt sensor is designed for detecting enough elevation for towing the vehicle. I'm not sure that it would be triggered by raising the car enough to pop the wheels.
re: aftermarket electronic installs. I took my wife's 07 sportage to MASS electronics to get the remote starter installed. Only place that Kia Canada has authorized for the installation (well as of a couple years ago anyway). I was really really impressed with the install. The tech gave me the show & tell before he put all the panel back.
I deal with Sam Guadagnolo, the service manager. He knew his sh!t as well. I don't know if he is still there or not.
