hey guys I just bought a ftra kit their website says that it will add 15-20 hp. Do you guys know if this is true or not? Wouldn't it be hard to tell how much hp on a dyno? If anyone here has it can you share your gains hp wise and track wise? Thanks

 

you cant tell on the dyno.. but i like mine! most people see 1-3mph gain

 

i dont know numbers but i felt a difference when i put it on.....its awsome
