like I said unless you are going standalone or piggyback you cant tune for sc or turbo on an 03.
If you havent already done so cruise over to
IonForums.Net has upgraded to phpbb3 there is lots of information to read up on that is specific to our cars, the cobalt is 99% similar but the is a lil difference especially with the 03/04's
I assume you have the qc which is the same body as an rl but without the goodies. That is what the baby blue ion with lambo doors you saw is.
If that is the case there is a lip kit for sale on there relatively cheap that is real good looking.
If you do register with IONforums here is a hint so that you get along with people and dont get frustrated:
Read the sections that pertain to your goals thoroughly, that way you wont go in and just start posting random shit thats been covered 15 times before.
We are harsh with our responces sometimes, dont take it to heart and get all pissy, and you will get the info you want.
