Guys--I've learned a lot from reading your "threads", but I need some advice. I have owned other vette's as a kid years ago and now have an 03 ZO6, totally stock. I drive it about once a week and while I enjoy "putting my foot" in it I don't race it on the strip; I do get on it down the highway here in north Texas. I love my car; so do my kids and grandkids. I drive it to Dallas with my wife on weekends so you understand conversation is important (I'm doing the listening). After reading and studying I am considering having LG Motorsports install LT headers and a Halltech stinger, with a before and after LS1 edit on their dynojet. Will any of this "throw any codes" or will this affect the reliability of the way my car drives on a trip of 300 or so miles when I take an over the road trip. Will I notice enough of a change to warrant the cost of the install? I do intend to keep this car because I love the style and difference of the FRC. Any thoughts anyone has about this is much appreciated.
