As soon as I get my stage II cp3 back from John @ Floor It diesel (which has been multiple months of bs saying it's ready since week b4 Thanksgiving and still not shipped yet) I will also have a set of 45% overs installed from Exergy. I've read changing valve springs makes a huge difference. Does that benefit the "built motor guys" only? I know in a gas motor you usually change springs due to a camshaft swap b/c of increased lift....
Thanks
