Alfa F154 2.9T ECU Tune

Alfa Romeo developed this 2.9-liter twin-turbo V6 together with Ferrari for the Giulia and Stelvio Quadrifoglio, and the relationship runs far deeper than a shared code: it uses the same 90-degree vee and aluminum-block architecture as Ferrari's F154 V8, essentially that engine with two fewer cylinders rather than a from-scratch design. Alfa adapted it with single-scroll turbochargers in place of Ferrari's twin-scroll units and both port and direct injectors for everyday drivability, real engineering choices, not just a rebadge. The result is the most powerful engine ever fitted to a production Alfa Romeo, and it gives the Quadrifoglio twins a genuine, verifiable claim to Ferrari engineering.

Given how closely this V6 is related to Ferrari's own turbocharged V8, Weistec calibrates it with exactly that level of care: an OEM-grade software recalibration, not a generic aftermarket tune, that keeps every factory safety system (knock protection, thermal management, full OBD diagnostics) exactly as the factory intended. The gain, from 505 to 580 horsepower and 443 to 503 lb-ft of torque, comes purely from getting more out of an engine the factory already built with real headroom, and it turns an already special V6 into something even more exciting to drive.
