They work, but as stated above, any time you change loads you have to retune to some degree. Most of the time when folks say they don't work it's because they've never bothered attempting to tune in a systematic way in accordance with the directions.
John
If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
