S58 Stage 1+ xHP

Engine + Transmission. ECU + TCU calibration

The Stage 1+ Package is a complete performance solution for BMW M vehicles powered by the S58 engine. 

It combines ECU tuning and transmission tuning into one fully optimized setup — delivering stronger acceleration, sharper throttle response, and dramatically improved shifting.

What you get

✔ Up to +150 horsepower (fuel dependent)

✔ Faster acceleration and stronger mid-range

✔ Sharper throttle response

✔ Faster, firmer, more responsive shifts

✔ Full driver control through MHD + xHP apps

This is not just more power — it’s how the entire drivetrain feels.

What’s included

Everything required for a complete Stage 1+ setup:

✔ DME unlock

✔ MHD ECU tuning (Super License included)

✔ xHP transmission tuning (Stage 1 / 2 / or 3 configured)

✔ Mobile DME removal and reinstallation

✔ Full access to MHD and xHP for future map changes

How it works

We come to you, remove the DME, unlock it, and return it ready to tune.

Typical turnaround: 5–7 business days

Your BMW stays with you the entire time — no shop storage, no towing.

When the DME is reinstalled, we set up MHD and xHP and configure everything for your car.

Why transmission tuning

Adding power without tuning the transmission limits performance.

xHP reprograms the BMW TCU to properly handle the added torque and power:

✔ Faster shift speed

✔ Firmer, more controlled shifts

✔ Better throttle-to-gear response

✔ Improved manual and sport mode behavior

✔ Increased torque handling

Your drivetrain finally works as one system.

xHP Stage selection

We install and configure the correct xHP stage for your setup:

Stage 1 — enhanced daily drivability

Stage 2 — faster, sportier shifts

Stage 3 — maximum performance-focused shifting

We help select the right one for your BMW.
