Anyone have older SCT X3/SF3 Tunes (LFU files)?

Hi all, I am checking all places that use the SCT X3/SF3 3015 programmer to tune their vehicles for any old *.LFU tune files lying around for the programmers? Reason is I recently updated my SCT SF3 to a new Firmware and new tune 2.101PFDUS and now my shift firmness adjustment is totally not working. SCT does not provide any way to revert to older Tunes... and I have 0 *.lfu files to go back as I got the tuner in 2011 when they already switched to auto update. Used to have tune XP 1.8.0 which ran great for years chirping tires 1-2.
