Description
TuneZilla 4.0 M177 ECU Tuning for Mercedes
Available through United Performance
TuneZilla calibrations are flashed through your vehicle’s OBD port with a FlashZilla device: read your factory file, download your chosen tune from the InstaTune server, and write it in. Switching between tunes or back to stock later uses the same tool.
Power & Torque
Factory baseline on TuneZilla’s dyno: 482 whp / 502 lb-ft — 603 hp / 628 lb-ft at the crank.

FlashZilla tool — the flashing device is required to load any of these files. Add it to your order from the FlashZilla Tool option above for $205.00 CAD; if you already own one, leave it set to No and only the software is supplied.
The tune itself is delivered as a software file for your own FlashZilla device — no parts ship unless you add the tool.
