I have a FAST intake and fuel rails sitting in a box getting ready for installation. I hear they're a PITA to tune and offer very little gains without the supporting mods. I'm really just looking to "bling" out my engine bay a little bit. I already have the HP covered with my CAI, Tune, LT headers, and Custom comp cam. My L99 is currently putting down 414 to the wheels. I'll be happy with 420HP after install and tune.
