So here's the deal, I have a 98 GTP that is bone stock.
In the next month or 2, I would like to do exhaust, intake, pcm, and 3.4 pulley.
-I have some questions....
1. What mods do i have to do before i can safely do the 3.4 pulley without breaking anything?
2. Is it worth it to get a downpipe along with my exhaust?
3. In lamens terms, what will a PCM do for me?
4. Are all these mods "tranny safe?"
5. Also, I need tires next month...Is it possible to go wider? maybe to a 235?
Any suggestions or info/opinions would be great, on the tires as well
