Jus bought my 04 gp gtp comp g and tryn to learn more about modifying safely to maintain proper daily driver usage.I traded in my 03 srt4 slightly mod for this car,it's obviously not as fast as the srt but an all around beter car in every way.it's sharp and completely stock,fully loaded and a great candidate for a sleeper.it's by no means slow and I kno the basics,I'd say it's begging to breathe easier before anything.after that im kinda not sure where to start and how to keep everything working properly without having codes being thrown..Any suggestions?
