So I have about 8k miles on my '13 ATS and I've been thinking about a tune for a little while now. I've read through tons of threads here on the subject and as I am learning I still feel behind the curve with a lot of the concepts and terminology.
With that being said, do you think as a newbie to tuning would it be a good idea to attempt to install one or have it installed??
