well after almost 400 miles on Saturday & almost 200 miles on Sunday. The TCI box I purchased from dingy performed flawlessly. So far the best money I have spent on my bike, other than tires. I have spent on it. Again thanks for all the help Gary. my gas mileage did improve from 32-34 to 38-39. now to get more miles on it today. I am thinking around 150 sounds like a good round number.
