HP Tuners and EFI Live do pretty much the same thing. They have cables that connect to your OBD port and then to your Laptop.

They can read the contents of your ECM, "copy" those tables and settings (aka the tune file), and then use their respective programs to make changes. Then, those changes are saved, and "flashed" back into the ECM.

Entry level cost is around $499, cost varies a bit between them and any licensing or credit costs afterword.

Be aware, while its great for people to learn and make changes, its very possible to blow sh!t up, or make changes that cause plenty of headaches.
