N54 Custom Tune (135i, 335i) MHD Flash
We also offer a custom map for your N54 engine, tailored specifically to your car if you're running larger turbochargers (e.g., 19T) or have made other modifications. It doesn't matter where you are in the world.
Process:
After your purchase, we'll contact you via email to discuss your wishes and modifications. To keep future contact as efficient and straightforward as possible, we suggest communicating via WhatsApp, Instagram, or messages on your phone. You'll then receive a base map, which you flash onto your car using the MHD adapter. Then you'll need to drive the car and send us a log file from the car so the tuning can begin. We'll send you back a modified file, and you flash it back onto the car. We'll do this until both parties are satisfied. Don't worry, we'll guide you step by step and take our time.
Important: To perfectly tune the map to your vehicle, you need the MHD Monitor license and the regular MHD license (Flasher). For boost pressures above 18 PSI, you also need the MBoost package.
