Always make a backup first! Luckily, the SCTFlash software I used would not let me write until I had saved current tune! I bricked my 5th gen a few times and being able to easily flash back to factory settings or previous tune was definitely needed.

Also with some of them you got to connect cable to laptop and OBDII before you turn on accessory. Obviously you don't want to actually start the engine if you're going to flash but most tuners work better if you connect the software BEFORE turning on the car as they typically hook into the boot routine to know when the init is done, read codes, params, etc.
