Seth is amazing at what he does. He is very upfront and honest. He doesn’t try and give you some cheap work around, he will only produce quality work. He brought my RX7 back to life and explain the process and kept me updated. He made my life easy in Okinawa japan when it came to my car. Very respected on the island and very trust worthy highly recommend. He works on all types of cars not only rotary. But he is a rotary master.

Great support from Seth. He knows his stuff and will be my #1 go to with my 13B. He has been patient and has answered all my questions, even with me being new to the rotory.

The owner was so friendly and helpful with fixing my front bumper that I had damaged from running into a pole. I didn’t want to pay the expense of replacing the bumper so he put everything back together so it was secure and safe at no cost. I am so thankful for his work.

Highly recommend Seth. Brought my Jzx90 to Seth for a stand-alone ECU. Seth got me the best deal on the ECU I wanted. I had a patch harness made to adapt my ECU to the factory chassis harness, Seth supplied the maker with all necessary information during the build of the harness. Toyota has some quirky things with fuel pump control which he troubleshot to avoid any issues with my larger pump and wiring kit (which he sourced for me). He then setup a base tune for the car and assisted me with logging runs throughout the week. I installed cams in the car (purchased through Seth) and he finished my map today. It’s a totally different car, the power is night and day difference and completely safe on AFR’s and Timing. I will be doing injectors and fuel rail next (also sourced through Seth) and look forward to working with him on the tune. Highly recommend Seth, one of the straightest shooters on island and makes things happen.

Wandering Gaijin Tuning has done nothing but great work! everything from an ecu to diagnosing and making a custom steering rack for me and shipping it to Alaska! Wandering Gaijin Tuning was my go to while stationed in Okinawa, and still is my go to for everything that I need for my FD! I highly recommend their services to include tuning parts and even custom ordered and powder coated parts! keep up the great work and service!!

wandering Gaijin Tuning it the place to go if you want honest no BS work done on your car. I hit him up about a year ago to get some parts sourced, he ordered everything I wanted but also gave recommendations that would make make my future projects go smoother. When it came time for tuning, he not only did an awesome job on the fuel system install, but he kept me updated through the whole process. when we found out that the aftermarket ECU I had sourced was bad, he was on the phone with tech support and emailing the company to see if there was any way to salvage it... The company said that it was bad, Seth was quick to get another ECU on order and kept track of it through shipping to try and minimize the cars downtime. Once the ECU came in he had it tuned and back to me in a few days! I have dealt with many of the car shops on this island over the years and the honesty and professionalism that Wandering Gaijin Tuning showed through the whole process will have me coming back to him as long as I own sports cars!

110% hands down most likely one of the best Tuning services you could easily get on Island!! Got my 93 RX-7 FD tuned and the performance difference is just insane. The FD wasn’t 100% ready and good to go when i brought it to him. Came across issues and they were fixed instantly. The knowledge and experience Seth has is nuts. He took care of me and my car and now its more than enough that i could ask for. He has the connects to all the good stuff that you could think about putting on your baby. I know for sure ill be going through him when i need to get upgrades. If you need a tune hit him up without a doubt.

Seth has helped me transform my 1993 FD to an absolute beast. I will never trust anyone with my car other than Seth. He installed my amemiya exhaust system, nee fuel system, turbo system, v-mount installation, powder coating and tune. His recommendations have always been spot on and does the best work here.

Just recently had some exhaust work done here as well as ordering a new aftermarket radiator for my WRX. Absolutely would recommend!
