Recently we have produced a 2016 Shelby GT350 with over 800WHP! Many of you have had questions on pricing and more information about the package that we offer and the specific gains. This package is called the S880 package and we see gains of up to 350hp and 240tq when used with 93 octane fuel! This can be done witht he stock clutch and stock transmission and is the best route to go and the biggest bang for your buck at around $11k installed! For any other questions you may have feel free to give me a call at 313-561-5500 extension 104, my name is Cody and ill be glad to assist you!
