Sameh S58 Custom Tune MHD / BOOTMOD3

Sameh Tune – S58

A custom tune for your S58 platform by Sameh — one of the most proven tuners in the BMW community, with multiple S58s running deep into the 8s. Each tune is built around your specific setup, fuel type, and driving goals. Pricing varies depending on configuration and fuel system.

Flex Fuel:
Optional but highly recommended. It allows you to fill up with any mix of 93 octane to full E85 without reflashing the car. The tune automatically adjusts based on ethanol content. A flex fuel kit is required for this feature.

Map Switching:
Optional feature that lets you change power levels directly from your steering wheel. Ideal for valet mode, different boost settings, or controlling power when someone else drives your car.

Custom Process:
Every tune starts with a base map and is refined through datalogging until the setup is fully dialed in — either when limits are reached or when you’re satisfied with the results.

Turbo Options:

• Hybrid Turbos: Stock-location upgraded twins such as Mosselman, Pure, Vargas, or any other stock replacement turbos.

• Full Frame / Top Mount Turbo: Complete turbo kits like BigBoost, DocRace, KLM, or any full-frame setup replacing the factory units.

Tuning Platforms:

• Bootmod3: After purchase, request the tune under the “Maps” tab in the BM3 app. Include your full setup and order number from EPC in the notes.

• MHD: You’ll receive an email after purchase with the next steps for setup and file exchange.
