Good luck finding this.  I would like to know as well.  
IIRC, I “think ” phunky said he was going to have the stock springs dynoed but he never posted the results (or was this in reference to something else, I’m a little confused actually).  Now he’s pulled the disappearing act.  Hope all is well with him. 
Does anyone here have a connection who will do a free spring dyno?  Next, we can see if any members are willing to donate their springs for a test.
