I'm assuming that you are scanning for knock? The reason I am asking is I was surprised to learn on my stock 04 gtp I had 6 degrees of knock. I would have hated to see what I would have had if I droppeds to a 3.5 pulley. Of course I didn't have any mods at that time and I see that you have a few. Do you have the most important mod anyone can have? A scan gauge for knock?
Yeah. Headers are the way to go. I did have the plog and dp and just put my headers on yesterday. like alot of people on these gp sites we start off with a few mods and then the next thing you know its hard to stop modding. Have you been to the track with that prix of yours? Stock my ran a 14.6
Thanx man its been a great car I love itDamn, this car looks great.
