Overview
The Quattroporte GTS uses the Ferrari-linked F154 3.8 twin turbo V8 and delivers huge real world gains when the Bosch ECU is calibrated correctly. This engine already has excellent factory performance, but there is still meaningful headroom in boost control, load targets, and torque intervention. Tuning mainly broadens the torque band and gives the car a much stronger surge without sacrificing the polished feel expected from a flagship sedan.
Key Features
- Ferrari-linked F154 architecture
- massive midrange torque
- strong high speed pull
- refined flagship sedan tuning
- excellent Stage 2 hardware response
