Product Description
This is the Maserati-tuned application of the F154 twin-turbo V8, the architecture Ferrari and Maserati engineered together and first fired up in the Ferrari California T. Dropped into Maserati's largest sedans and SUVs, the Quattroporte, Ghibli, and Levante in their Trofeo and GTS forms, it stands as Maserati's most powerful factory engine option, real Maranello engineering built by Ferrari itself and installed straight into the brand's flagship models.
Weistec calibrates the Maserati-spec F154 with the same engineering discipline Ferrari applies to this architecture everywhere else it appears: a full software recalibration, not a piggyback box, that leaves the block, turbos, and internals exactly as the factory built them. Every OEM protection (knock protection, thermal management, full diagnostic compatibility) stays fully in place while the tune wakes up real performance the factory left on the table, taking output from 523 to 585 horsepower and 524 to 620 lb-ft of torque, and putting this flagship V8 firmly into another league.

Complete The Upgrade
An ECU tune alone won't remove all factory limits or fix how power reaches the ground. Add these to round out the upgrade with no limitations.

What is a CPC module?
The CPC (Central Powertrain Control) is a separate control unit that manages things like the active exhaust valves, radiator fan, intercooler pumps, and speed limiter. On many newer Mercedes-Benz vehicles, it also houses torque limiters that can hold back an ECU tune from reaching its full potential.
What is a TCU tune?
A TCU (transmission control unit) tune delivers faster, firmer shifts with higher line pressure, reducing clutch slip and increasing the transmission's torque capacity. It's a worthwhile upgrade on its own, or paired with an ECU tune for a fully sorted powertrain.
Good to Know
- This is a reflash of your original module, not a stand-alone unit.
- Power gains vary by vehicle, modifications, fuel, and operating conditions (ambient temperature, altitude, etc.).
- New or upgraded spark plugs are always recommended when tuning.
- Product may not be emissions compliant. Check local laws prior to installation.
- Always use a battery charger during programming.
