Sameh B58 Custom Tune MHD / BOOTMOD3

• A custom tune for your B58 built by Sameh — one of the best tuners on the platform, with multiple B58s running in the 8s. Pricing varies depending on your setup.

  Flex Fuel:
  Optional but highly recommended. It allows you to run any mix of fuel — from 93 to full E85 — and the tune will automatically adjust without needing a reflash. A flex fuel kit is required for this feature.

  Map Switching:
  Optional feature that lets you change power levels directly from your steering wheel. Perfect for valet mode or when someone else drives your car — you can control how much power each map delivers.

  Custom Process:
  Each map is built specifically for your car. Tuning starts with a base map and is dialed in through revisions until the setup is fully optimized — either when limits are reached or you’re satisfied with the results.

  Supported Platforms:

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

  • MHD: You’ll be contacted by email after purchase with next steps.

All tunes are final and non refundable.
