I need help!! I have a 2008 EFI Mastiff with a new (in 2013) S&S VFI module. Never right since install it would lose tune constantly. The shop working on it for the last 5 months is giving up on it. They burned up the clutch on the dyno trying to get it to run right. I'm in Mansfield, Ohio 1hr from Cleveland, Columbus, or Akron. Is there anyone in Ohio that can tune this thing?
