Honestly, I don't know. But I'd guess it is either the motor itself is weak or the lift strut is not helping enough. 

If I am not mistaken, that update is for the tuner itself, not the tune.  You need to contact them to check if there is a tune update. If there is, then they can push them to your tuner. 

Just plugged in the LMS module to the computer and version 37 is out. How do we know what the changes are?

You lift out the tray.

Is the part coming from Canada?

Finally got the time to install the rotors and pads I got in June on my ST.  Not that hard to do if you have the right tools.  The 7mm and 11mm Allen sockets and the 18mm standard socket are not normally found in most tool sets you buy.  A 1/2 inch impact wrench is also a good idea to have for the job. I can't find the thread here, but the idea to use a bolt through the holes for the anchor plate to remove the rotors is spot on.  Both front rotors would not budge using a rubber mallet. I only had time to do the break in.  So I cannot comment on how they function yet.  The front pads had a lot of life left and the rotors were in pretty good shape.  The rear pads were completely worn out and needed to be changed. I'll report back on how the brakes perform.  

Whoa, ho, ho. After reading Omar302's post, I did some more digging. Seems Levittown was wrong. (But not me, of course .... :-)   Here's what I'm finding now;   "ML3Z-19A361-A is the part number for the Ford Perimeter Plus Vehicle Security System, a shock and impact sensor module.   After a simple plug-and-play installation, the module automatically activates with an ignition cycle. Dealer programming is only needed if you want to add the optional remote start feature."   So ill just sit here on the patio, feed the squirrels and hummers, drink my martunies and think happy thoughts.    Let us know if you decide to go ahead and put one in.

I just cleared the codes and ran several RGTM self tests. I am receiving no DTCs during a normal operating cycle or on a cycle when I am getting no action from the liftgate at all, which is the most common pattern after the first normal cycle. When the liftgate "shrugs" I am getting the below DTC:   Code: B1515 - Tailgate/Liftgate/Boot/Trunk   Additional Fault Symptom:  - Commanded Position Not Reachable   I also performed 6 RGTM reboots and the liftgate operated normally after 4 of the reboots and "shrugged' after the other 2. I at least got some sort of response from the liftgate immediately after rebooting the RGTM. 

Consider obtaining a copy of TSB 13-6-18. This specifically deals with a current draw due to the remote system keeping the electronics awake. Sometimes it just requires a software reload/update.   As you have isolated the problem to the RF module, there's three possibilities. The module, wiring becoming grounded and a faulty RF hub. Most likely cause is the module has failed. (Shorted wiring would cause the battery to drain much faster & network issues would probably affect several other devices.)   I've read in another forum where it was traced to water entry getting into the module. Caused it to stay on.
