The latest tuning program for the Nissan GT-R comes from Switzer Performance as this week they've unveiled the P600 PKG that increases the output of the engine from the standard 545 hp to 600 hp. To gain the extra power, the tuners had to install their own high-flow filters, a free-flowing SS90 exhaust and update the ECU software. That new exhaust system also makes the powerful twin-turbo V6 3.8-liter engine sound better. Thanks to these hardware modifications, the 2012 Nissan GT-R P600 PKG by Switzer Performance can do the 0-62 mph sprint in only 2.6 seconds. There aren't any styling changes to the GT-R but at least the car now rides on a fresh new set of Switzer Signature series lightweight forged aluminum wheels wrapped around in Michelin Pilot Supersport tires that according to the tuner improve the vehicle's handling capabilities and also provide a better ride quality. All these goodies are priced at $12,990.
