Mike's Stealth Grey Focus RS on the dyno this afternoon to see what his new Precision Turbo & Engine NX2 turbocharger and Xtreme-DI LLC HPFP35/2000cc injector combo is doing for us! This car is still using the original engine with 55,000 miles, all the bolt-ons from Extreme Turbo Systems, and an Advanced Clutch Technology FF5-HDSS organic clutch to take the abuse.

Justin Brasil at Freektune got it dialed-in on pump gas with 407whp/411wtq and added some ethanol to the tank to see the full advantages of this turbo/fuel system. Www.freektune.com

This car exceeded our usual goals, making 443whp/446wtq so we dialed it back to 424whp/427wtq where we believe this engine will live a happy life for Mike to enjoy as his daily driver.

Thanks to JP Alonso at Edge Autosport for offering his support to fill the demand of Precision turbos here at the shop! Www.edgeautosport.com
