Description
Weistec Engineering ECU tune for the Porsche Cayenne (2025) with the Twin Turbo 4.0L V8 (EA825). Weistec’s crank figures put the tuned engine at 567 hp and 592 lb-ft, up from 468 hp and 442 lb-ft stock, from a recalibration of the factory ECU software.
Key Features:
- Up to +99 hp / +150 lb-ft: Weistec’s crank estimate of 567 hp and 592 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.
- Reflash of the factory ECU: the original module is recalibrated rather than replaced with a stand-alone or piggyback unit.
- What changes: improved throttle response, optimized fuel and spark, increased boost and top speed limiter removed.
- Tuning method: Cypher Pro Dealer: installed through a certified Weistec Cypher Pro dealer.
- ECU unlock required: the ECU has to be unlocked before this calibration can be flashed.
Fitment:
- Porsche Cayenne S 2025 (PO536-FL) – Twin Turbo 4.0L V8 (EA825)
