Rspec Tuning This page is dedicated to the engine management tuning work of Rspec Engine Management Tuning led from the heart of the Pacific Northwest.

R.Spec tuning has been calibrating for over 10 years. With every single tune done, I strive to find pathways to improve upon my past products and outcomes. Every car needs to be customized to the individual’s style and driving habits. However each car has a personality and characteristics that it responds to. There is a happy medium between the two, and that is where I come into play. When you hir

e me to tune your car, you are trusting in my ability to decipher how your car will react and function based upon my knowledge. At that point I will adjust your car to what I deem necessary to accomplish in giving you the best, longest lasting, and most fun end product. I am always willing to work with you in reaching an end goal that will make you satisfied. As of now I specialize in Subaru’s and have a wealth of knowledge pertaining to them. I have worked in the industry for the past 7 years and with over 1000+ tunes completed, I have elevated my understanding of them immensely. Do not hesitate to contact me with unique projects of other makes and models though. Including but not limited to:

Subaru | Scion | Mitsubishi | Nissan | Mazda | Infiniti | BMW | Ford | Chevy | Audi | VW | Honda | Datsun | Toyota | Etc

I don't post often, but it's because I'm staying extremely busy. Multiple cars everyday 5 days a week not including eTunes.

Been kicking around the idea of offering mechanical service work as well. That would require me hiring an employee to turn wrenches. Is this a service you'd like to see me offer?
