you can go ahead and get a custom tune whilst the car is completely stock and get a bit more power on it, never heard of these things 'needing'a tune at a particular time in its life I would suggest you get together all your parts and have it tuned in one go, save the mulah that way
you should be able to pick up an 03-04 model for around 20k even under if you haggle a little, $5k can go along way with these beast!! as mentioned, do some research, ask the questions, wont go wrong here mate
happy new year boys, all the best for the next what did we think about the fire works,, I didnt mind them this year, hate that 'fuzzy' chick that was presenting though!!
lets give them a chance, suppose as long as they dont lose their great personalities and be overwhelmed by the high flyin, high roller life of a Mod!!!
