First off new to the form and all info is appreciated! As title states I'm going to be installing a frx and hpx from riffraff soon my main question is what are the pros and cons of the higher and lower springs in the frx kit I know they regulate fuel pressure but why wouldn't you want to use the spring that creates the most fuel pressure I'm sure there is a great reason why im just curious and wanting to know more before installing?
