We had previously tuned this 2010 L99 a few years ago, with just the Magnacharger TVS 2300 and Rotofab. Itching for more power, it now has a set of Kooks 1 7/8″ headers to help exhale much better. After a set of Fuel Injector Connection 1000cc’s and some retuning, it’s now making 500rwhp & 557 ft/lbs tq through the stock automatic!
