Got to take the gt500 to the dyno bone stock it put down 476hp 471tq with just over 10psi of boost. I got a k&n filter and ford racing resonator delete from a friend who upgraded to a jlt setup and changed it on the dyno just to see the gain and it netted 485hp 476tq. I seen the boost hit 11 for a split second also on that run. Also the stock tune was on the fat side.
