If you are new to tuning or new to Subaru performance, you can gain much insight into the program by sitting down and reading these sections. Then, contact SPD Tuning Service with specific questions. We are always glad to help you extend your personal knowledge.

"Information is free, parts and labor are extra."  We mean to help you understand what is possible, and in turn, when making your purchase, we ask that you think of us and the special effort we have made in presenting this information to you.

No matter what you do to the car, you are going to have to develop a budget, an amount of money it is going to take to get the job done. What SPD Tuning Service can help you decide where the money should go, in what order, and perhaps just as important, where it should not be spent. The idea is to have each step build on the previous step (money spent) and give satisfying results. These FAQ type pages make it possible for you to develop a realistic tuning program. The most important concept to understand about SPD Tuning Service is that you "own" the tuning program. We are not here to separate you from your money. The service is designed so that you make informed discussions about the level of performance you build into your car.
