New mods for the 05

Anyone played around with modifying there new stang? yeah 305 is nice but i think more lik 390 be a bit better lol Steeda has stuff out springs performance and i think the 4.6's mods from previous years would prob work don't yall think? like the throttle bodys and water pumps and so on.. hopefully because im sittin outside my house waitin for a new 05 to come thumpin by (i live RIGHT next to a major highway buh i get to see hotrods n stuff lol)
