There is a local shop that does it and of course they say it works, they claim a 50% increase in strength. My wallet is usually pretty light so I don't know how much of a performance gain will had from lightening it up more. If you had the cash on the table to cryo treat say your block, crank, and factory rods or spend a few more bucks on a set of billet rods where would the money be best spent? This is part of my longer term performance upgrade list after saving my pennies I just really don't want to throw money at stuff where it is not needed.
