More Power Without Giving Up Daily Comfort: DTE PowerControl X for BMW 40i Models
29th Jun 2026
BMW’s modern 40i lineup occupies a unique place in the performance world.
Vehicles like the 740i, X5 xDrive40i, X6 xDrive40i, and X7 xDrive40i already deliver smooth power, premium comfort, and the versatility expected from the B58 platform. For many owners, the factory setup feels quick enough.
Until you realize how much more potential is still available.
That’s where the DTE PowerControl X comes in.
Now available at XPH, this advanced plug-and-play tuning module was developed specifically for the latest generation of B58-powered BMW models, delivering substantial increases in horsepower and torque while preserving the refinement and usability that make these vehicles so enjoyable every day.

Unlock More from the B58 Without Changing the Character of the Vehicle
The B58 has built a reputation as one of BMW’s most capable turbocharged engines.
Its broad torque delivery and strong factory engineering make it an ideal candidate for intelligent performance upgrades.
PowerControl X enhances that experience by increasing output without requiring permanent ECU modification.
Performance gains of up to:
- +87 horsepower
- +107 lb-ft of torque
translate into improvements drivers feel immediately:
- Stronger midrange acceleration
- Quicker overtaking response
- More effortless highway merging
- Sharper throttle behavior
- Increased confidence under load
The result isn’t a completely different vehicle—it simply feels like a more capable version of itself.
Performance That Adapts to How You Drive
Not every drive calls for maximum output.
One of the standout features of PowerControl X is its ability to adapt performance delivery depending on driving conditions and personal preference.
Drivers can choose between:
Sport Mode
Sharper response and stronger acceleration for a more energetic feel.

Designed to maintain smooth operation while prioritizing everyday usability.
