DIGITAL TUNE DELIVERY
The tune itself is delivered by email. No physical tune is shipped, and no tracking number is expected.
- Your calibration file and applicable flashing instructions are sent to the email address used at checkout.
- Complete the Tune Configurator for the car exactly as it will be when flashed, and review every selection before checkout.
- A full ECU read is not required unless Poverty Built requests one after reviewing the order.
- Flashing software, licenses, cables, and interfaces are separate unless this listing or your order specifically says they are included.
- If your order also includes a cable or other physical hardware, that item ships separately. A shipping label means the package is being prepared; it is not in transit until the carrier receives it.
Unlock the full potential of your BMW N54 twin-turbo inline-six with our dyno-tested ECU calibrations. Each stage is designed to provide optimal power gains while maintaining reliability, with maps available for 91, 93, 95 pump gas and ethanol blends (E30, E50, E85).
Flashing options: Supported maps can be delivered in an MHD-ready format for flashing through MHD. You may instead choose a Bimmer Tuning Tools N54 QuickFlash-compatible file or another supported format for your preferred compatible flasher. If Poverty Built needs a file read for the ECU/ROM, we will request it; a full read is not required unless asked.
THIS IS A TRUE OTS MAP PACK
For this product, the stage is part of the calibration specification. Choose the stage that matches your turbo setup, supporting hardware, and fuel. Anything labeled Required Mods must be installed for that map. Items labeled Recommended Mods improve consistency, response, or reliability but are not mandatory unless the stage specifically says otherwise.
This pack is designed to compete directly with the familiar MHD map-pack format: a more affordable, performance-focused set of ready-to-flash maps with stronger power targets where the listed hardware and fuel support them. It is not a bespoke, revision-based custom tune.
Tune Configurator choices are selected separately. Choose the exhaust/overrun behavior you want from the available Tune Configurator. Your Tune Configurator selection does not change the stage and does not replace any required hardware or fuel requirement.

✅ Boost levels and ignition timing optimized for maximum performance while maintaining drivability
Required Mods:
- All Stage 2+ requirements
- Upgraded turbos (PS2 or 19T hybrid turbos)
- Upgraded low-pressure fuel pump (LPFP) (Walbro 450+ recommended for E blends)
- Aftermarket turbo inlets & outlets (for improved airflow)
- Methanol or upgraded high-pressure fuel pump & direct injectors (for full E85 support)
Recommended Mods:
- Larger charge pipes and intercooler (for consistent IATs)
- Aftermarket exhaust system (for improved flow)
- Upgraded clutch (for manual cars)
Notes:
- Power figures are estimated and may be inaccurate by a percentage and vary based on fuel quality, supporting mods, and climate conditions.
- All tunes retain OEM safety features and fail-safes to protect engine longevity.
- E30/E50/E85 blends require proper fueling upgrades to prevent fuel pressure drops.
