Well like the title says. I've had my 03 gtp since nov. 08. So about 6 months. When I bought it it was bone stock inside and out all the way down to the paper filter. Since then I've traded my stock 16s for 18s, scuffed them down to bare metal and painted them black. I put a supercharged decal on my upper windshield. Traded my black grille pieces for brushed alluminum ones. Bought new headlights and got clear corners with clear turn bulbs. Then I've got a 3" dp without cat,brand new gtx exhaust tips that look awesome. I got a cai kit for cheap off of craigslist. Bought a tb spacer and 180 tstat. The stat works well amd was a good upgrade. I bought my pcm from bluegtp91 or nick which helped a ton. And I've got a 3.4 pulley with gatorback belt. I just put my 8.5 mm wires and autolite colder plugs in the other day. I have a plog for the car just haven't put it on yet. But I guess I'm sayin I love this car and its been good to me ever since I bought it. It seems like every power upgrade I do gives me friggin 20 horsepower lol! I'm gona try and post pics up if I can. Everyone on here has been great also. Lots of good advice. Grand prixs rule
