Our calibrations are written to keep the vehicle inside manufacturer specification — nothing is pushed past what the hardware was designed to survive, and a back-to-stock file is archived for every car we touch. That said, warranty outcomes are decided by your dealer, not by us, so speak to them if warranty coverage is critical to you.

Do I ever need to be re-tuned?

No. It's a one-time tune for life. If you add hardware later and want the calibration revised, talk to us — but the tune itself doesn't expire or need renewing.

How does the Shipout Method work?

You send your VIN and a photo of the ECU label. We build and ship a pre-tuned ECU. You unplug the old one, plug the new one in — minutes, no tools — and send the original back with the label included in the box. Zero downtime.

What is the CTZ Flasher?

A handheld ECU programming tool controlled from an iOS or Android app. It reads and writes your ECU at home, stores multiple profiles, clears trouble codes and returns you to factory with one tap. The tool and the tune are sold separately.

Can I go back to stock?

Always. Your original calibration is read out and archived before anything is written. Back-to-stock is one flash away, whether you do it yourself on the flasher or send it to us.

Do you really improve fuel economy?

On most vehicles, yes — customers report up to an extra 200 km in the city and up to 350 km on the highway per tank. Results vary by vehicle, fuel quality and how you drive it. If you spend the extra torque instead of saving it, your mileage won't improve.

Which vehicles do you support?

22 marques and counting — the Chrysler group in depth, plus BMW, Mercedes-Benz, Audi, VW, Porsche, Ford, GM, Toyota, Lexus, Nissan, Infiniti, Hyundai, Kia, Mazda, Honda, Acura, Jaguar and Land Rover. If yours isn't listed, send a Special Tune Request.
