Becoming a good tuner and especially opening and operating a good shop is an extremely difficult path and something you have to go into slowly. You have to get a very good understanding of engine dynamics, turbo systems, software systems, and finally customer service and business management skills.

Finally, while it may seem that tuners/shops make a lot of money, that is usually far from the truth. Most shops barely make enough to stay in business and take home a little money at the end of the day. The first few years of opening a shop are very expensive and most shops do not make any profits for at least 3 years. If you're going into this field based on money, you are making a big mistake. You have to have serious passion for this type of work to make it worth it.
