A very smart thing I heard once was tune to performance not temp, reason why is most engines only need temp check in break in or when you have it feeling right and want to see where it's at. If its running hot you should know by the bottom end feel, if it does a whuuhh whuuuuhhh sound instead of a brap sound richen it up, if its loading up or just flooding then u need to lean the top to where it cleans out. Have it running clean but not lean.
