H&S OD speed issues

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?


2010 F350 CC SWB FX4 loaded... Truxx leveling kit with an Icon adjustable trackbar, 20X10 XD Monsters with BFG 285X65X20 AT KO's, S&B intake, H&S Blackmaxx with DPF/Cat delete and MBRP Cool Duals, SD card full of KEM tunes that sits (unused) in the console. Audio by Focal, Audio Control, and JL Audio...

Yeah, either back off to a lesser H&S tune thats ideal , or wait for H&S to make an adjustment that happens to correspond with your needs or Time to invest in the 345 KEM and work with Mike till you get the results you want.

I have the 45mph lock up and if I stay above 45mph it stays locked up. I'm running the Hot Damn file.
