Weistec Engineering – Mercedes-Benz M276 ECU Tune

Description

Weistec Engineering ECU tune for the M276-powered Mercedes-Benz models (2013-2023) with the Twin Turbo 3L V6 (M276). Weistec’s crank figures put the tuned engine at 438 hp and 521 lb-ft, up from 328 hp and 354 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +110 hp / +167 lb-ft: Weistec’s crank estimate of 438 hp and 521 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.
