Masata Plug & Play Tuning Box for BMW G80/G82 M3 & M4 (S58) 2021+ | Piggyback Performance Upgrade Up to +66hp/+76Nm | M3/M3 Competition, M4/M4 Competition | MST7000

Unlock serious performance from your S58-powered BMW M car with the Masata MST7000 add-on power module. This intelligent inline control unit delivers rapid, repeatable gains without opening the ECU, giving your G80 M3 or G82 M4 a harder midrange, stronger pull and crisper accelerator response. If you want a removable tune that feels OEM-plus, this is the upgrade.

What you get from the Masata MST7000

• Up to +66 bhp and +76 Nm, transforming real-world acceleration and in-gear punch
• Noticeably sharper throttle behaviour and reduced turbo delay across the rev range
• Five selectable calibrations so you can tailor the power delivery for road or track
• Start stop compatible for everyday usability
• Fully reversible fitment for a dealer-friendly setup
• Sealed, weather resistant aluminium casing designed to handle British conditions
• OE-style harness with factory connectors for a clean, reliable install

We have fitted and run this module on customer G80 and G82 cars at MJ Modifications, and the feedback has been outstanding. The S58 responds brilliantly, with a noticeable surge in midrange torque that makes overtakes effortless while keeping daily drivability smooth and predictable.

Why this upgrade suits the S58 platform

The Masata MST7000 is engineered specifically for the S58 twin turbo engine. It is the ideal choice if you want a safe, reversible power increase without a full ECU remap. Whether your car is stock or lightly modified, the selectable maps let you choose the response you prefer for fast road or occasional track use.
