GM now allows us to us our tech2 scan tools for programming with SPS2. This is great for the older class 2 communication vehicles. Many newer programming devices are too fast or deliver the programming at the wrong time so it is best to use an older J2534 device or better yet the TECH2. You will need a functioning TECH2 scan tool ( I have not tried this with tech2 clone), You will need the DB9 serial to RJ45 adaptor, rj45 cable, a usb to serial Skyspan adaptor if your laptop doesn't have the DB9 serial port.
