ok so which one of the hp tuner set up's would i want to buy? and also do they hook up to the fords or the dodges if you buy the credits or do you need a diff hp program for them? and pretty much what i need to do is just buy hp tuners go to the forum and learn from there? i just read the how to write up from the other nick and it doesnt seem to bad but im sure theres alot more to it once u start diggin around more
