It's really easy to install and it goes step by step.

Had to download their update drivers, that was a big hassle. Then had to install updates to programmer. (8hrs later) After all, that updates failed. It's been 2 weeks and still not installed on my truck. Tried SCT Performance emergency weekend tech. support, no answer. Sent e-mail to SCT, no reply.
