I guess what I'm saying is that the folks who make the consumer stuff are different than folks who make the customs. While the TF10 is part of UE's history, replaced by the UE900 recently, the UE factory in Irvine didn't seem to have much to do with the UE900 (or below), other than probably providing the mothership Logitech, its expertise. In other words, there seems to be a Logitech/UE and a dedicated UE (customs.)
Trying to tweak a TF10 (now discontinued) into having performance more similar to the UERM (in an attempt to make whatever confused statement, i.e. "UERM is a rip off", "TF10 is really a UERM gimped", "UE is ripping us off", etc.) is like trying to add engine and suspension mods to a Toyota MR-S (also discontinued) to make it perform like a Lexus LF-A. And yes, I surmise it's possible with mods to make the MR-S faster or at least very close to the LF-A on more technical tracks such as Buttonwillow or Streets of Willow Springs. But that completely misses the point of Lexus.
