Updating the tuner online ate up the most time for me. One I don't have a personal non-Apple computer, so I had to do the update on someone elses. The forum with the updates is fairly unclear about which files are the most up to date within the 6 pages of posts. After these initial issues the installation on the actual vehicle was quick and easy. The tuner paired with a CAI seems to yeild a more aggressive vehicle. The code reading/clearing is reason enough to purchase the product.
