Honestly, I am very impressed. You can feel the difference right off of idle, The motor revs quicker and throttle response feels more crisp. The only complaint I have is My headlamps are slightly dim at idle, but My idle is at about 500 rpm.(easily changed with the Gryphon) If idle is in the 600-625 range all is good. I watch my voltage on My Gryphon and it never goes under 13V even when the efans are on at idle. I have a pic of them on My first post in this thread.
