Yo! i was reading the forums and whatnot, and i came across a post where a guy wanted to spend some money on his focus. Most of the replies included a tune. Now, since i am a little kid, (18), and just into focus' and cars in general, i would like to know around how much tuning will cost me. And i'm also guessing that this will help with my cold air intake, short throw, and full cat exhaust, no? Thanks for the input, i know that it's going to be from wayne, since he seems to be the favorite.
