I need some advice on programming my truck. I've got a 2004 f-150 with 5.4ltr. I've had this Hypertech programmer since I've had my truck, bet never really knew much about it. I was wondering if anyone could tell me the best settings for programming my rev limiter/shift points? I don't know whether it makes a difference or not but I also have the cool air induction and throttle body spacer. Please share your settings if you think they're the best for the 5.4. I live in the country, with alot of steep grades and hard turns.
