Description
Weistec Engineering ECU tune for the Porsche 911 (2021-2024) with the NA 4.0L Boxer 6. Weistec’s crank figures put the tuned engine at 523 hp and 362 lb-ft, up from 503 hp and 347 lb-ft stock, from a recalibration of the factory ECU software.
Key Features:
- Up to +20 hp / +15 lb-ft: Weistec’s crank estimate of 523 hp and 362 lb-ft, from Dynojet testing; real gains depend on fuel, conditions and supporting modifications.
- Stage calibrations: W.1 (Stock Vehicle) and W.2 (Race Exhaust fitted), so the calibration matches the hardware on your car.
- Optional add-ons: Porsche PDK TCU Tune (992), each selectable when you order.
- Reflash of the factory ECU: the original module is recalibrated rather than replaced with a stand-alone or piggyback unit.
- What changes: optimized fueling, optimized ignition timing and removed speed limiter.
- Tuning method: Cypher Plus: flashed at home from your phone with a Weistec Cypher Plus.
