Description
Weistec Engineering ECU tune for the M176-powered Mercedes-Benz models (2016-2023) with the Twin Turbo 4L V8 (M176). Weistec’s crank figures put the tuned engine at 550 hp and 575 lb-ft, up from 416 hp and 450 lb-ft stock, from a recalibration of the factory ECU software.
Key Features:
- Up to +134 hp / +125 lb-ft: Weistec’s crank estimate of 550 hp and 575 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: CPC Module (2019+), 9 Speed TCU Tune (2019+) and 7 Speed TCU Tune (Pre-2019), 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: improved throttle response, optimized fuel and spark, increased boost and top speed limiter removed.
- Tuning method: Cypher Plus: flashed at home from your phone with a Weistec Cypher Plus.
