Description
TuneZilla N55B30T0-355HP ECU Tuning for BMW
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.

Factory baseline on TuneZilla’s dyno: 355 whp / 343 lb-ft.
- Stage 1 — 395 whp / 402 lb-ft (+40 whp / +59 lb-ft over stock)

Fitment:

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.
