Welcome to Project F-150! I must say that I have been more than impressed with the overall handling, performance, comfort, styling, etc. That is not to say there is no room for improvement...priority number one is...BETTER MILEAGE! I know I am not the only one to make this comment. Other modifications, as well as future modifications, fall into the categories below. It's been going slow, but check back often to chart the progress. Thanks!
