About Us

GTS Performance started in 2010 as Gonzo Tuning, back when remote tuning was still a strange idea to most people. The goal was simple: build tuning that actually worked, support customers properly, and skip the nonsense.

In 2013, Gonzo Tuning was rebranded as GTS Performance. The name changed, but the approach did not. We have always focused on real results, honest advice, and software that makes your car better to drive — not just better on paper.

We specialize in ECU software for Volkswagen, Audi, and Porsche platforms, with support that is based on actual platform knowledge, not generic one-size-fits-all tuning. That means understanding the differences between engines, ECUs, hardware setups, fuel quality, and what the car is actually being used for.

Over the years, we have helped customers all over the world through remote tuning, making it possible to get properly calibrated software without handing your car over to a local shop that may or may not understand the platform. If you have a laptop, the right cable, and a little patience, we can usually get you where you need to go.

We are not interested in flashy claims or inflated dyno fantasy. We care about safe, effective, well-sorted tuning that matches the car, the hardware, and the owner. Sometimes that means more power. Sometimes it means smoother drivability, better throttle response, cleaner cold starts, or getting a specific setup dialed in correctly.

What sets GTS Performance apart is that we are deeply involved in the platforms we support. This is not a generic software catalog. It is years of hands-on experience with VW/Audi/Porsche engine management, troubleshooting, hardware combinations, and the weird edge cases that show up once you get beyond basic bolt-ons.

Whether you need a straightforward Stage 1 file, a remote tuning solution for a modified setup, or guidance on choosing the right software for your engine code, GTS Performance is built around one idea: give people tuning that is correct, usable, and worth paying for.

From Gonzo Tuning in 2010 to GTS Performance today, that has been the mission from the beginning.
