Would suggest you do some internet searching, especially with YouTube. There are some straight forward, easy, and excellent how-to videos on explaining the proper procedure and setups using WDH and fine tuning them. You may find fine tuning them yourself is better than what the dealers would do. I did my own setup using the Videos and am very glad I learned how. As some here have repeatedly stated, they don't trust the dealers with the WDH setups. Check out the Videos, you will be ever so glad you did.
