Romeo Ferraris has introduced a new tuning program for the Ferrari 599 GTO.

Starting with the engine, the company installs a high-flow air filter and a sports exhaust system. These minor changes enable the model to produce 685 PS (504 kW / 676 hp) and 633 Nm (467 lb-ft) of torque - an increase of 15 PS (11 kW / 15 hp) and 13 Nm (10 lb-ft).

If that isn't enough, there's a stage two package which adds a revised ECU and a different exhaust system. This enables the 6.0-liter V12 to produce 710 PS (522 kW / 700 hp) and 668 Nm (493 lb-ft) of torque - an increase of 40 PS (29 kW / 39 hp) and 48 Nm (36 lb-ft).

Customers can also order a variety of carbon fiber accessories including mirrors, a rear diffuser and a front splitter.
