People often criticize remote tuning (e-tuning) for its inherent drawbacks versus dyno tuning. However, these same people also often forget about what makes remote tuning so amazing - and that is the ability to work with clients from across the world 🌎

hit us up for an e-tune all the way from Costa Rica! Thanks to and their Phone Flash software, we were able to answer the call. Herald is actually one of a few of our Costa Rican clients, and it’s an honor to have a presence in Central America 🇨🇷

Thank you, Herald, for allowing us the ability to be a part of your journey. Wishing you many worry-free miles and plenty of delicious Gallo Pinto along the way 🫡

In a sea of ‘bolt-on’ and ‘stage’ builds, sometimes you have the opportunity to work on a more bespoke project - one that turns your brain on and provides you with a challenge 😏
vollmar was one of our clients from back in our Subie Clinic days. From humble beginnings with a factory powertrain and automatic transmission, this build has manifested into an absolute gem. Drivetrain swaps, PCM swaps, and a variety of performance parts - all installed at home with relatively limited tools and resources. For that, this build and its owner have our utmost respect 🫡

Shout out to Robert and thank you for bringing this amazing project to us for its final touches 🙏
