I've been running the new efi live update. I simply disabled the TCC slip limit function all together and it works absolutely flawless. I still have my BT lockup box just in case but so far for the 2 months I've been running the tcm tune...I see no need for the lock box anymore, unless you were a sled puller and needed to force unlock.

I can cut identical times with the tcm tune as I can with the lockup box. I prefer the tcm tune more than the lock box as well.

I don't know what the cost difference is between them, but I have had nothing but good results with the BT L/U box, I love it:thumb:

Same here lol have a fleece box sitting here awaiting install. Also have Ben's box on another truck and when installed CORRECTLY that thing is such a great engineering accomplishment.
