Italian tuning firm Romeo Ferraris has prepared two stages of performance kits for the
Nissan GT-R, boosting power from the 3.8-liter V6 to 485 and 530 horsepower, respectively. Based on the GT-R from model year 2010 or 2011, Step 1 includes the replacement of the standard air filter and the installation of a new programmable module with three pre-set power settings (Normal, Sport and Race) that can be selected via controls on the car's steering wheel.
