S58 Custom Tune

Real S58 Calibration. No Fake Numbers. No Guesswork.
Built around your setup. Refined through real data. Delivered properly.

This isn’t a file you download and hope for the best. You get a calibration built around your exact car — hardware, fuel, and how you actually drive it.

From stock turbos to big setups pushing serious power, whether on pump fuel, ethanol blends, or full flex, we set it up properly.

We don’t chase dyno numbers to impress the internet. No lean runs, no excessive timing just to print a number. The focus is real power — consistent, repeatable, and proven both on the dyno and on the road.

No shortcuts, no inflated figures, just proper calibration that holds up in real conditions.

Up to 4 switchable maps available depending on your setup. Fully supported on MHD Tuning and bootmod3.
