I've loaded the hot dam tune on my 2010 with the 45mph lockup, and the converter just hunts (locks-unlocks) with any movement of the throttle. I loaded up the 50mph lockup, and it works fine, but doesn't lock until 60mph. I then loaded the 55mph lockup, and it locks at 60mph. I called H&S this morning and talked to Dan, and he basically said "that's the way it is". Seriously??? He then said to try the race tunes with ladderbars. What the hell does that have to do with the TC lock up speed? Anyone else have any satisfaction with H&S, or do I have to spend more $$$ with some KEM tunes?
