I have the TL2010Q, which is the upgrade but still very similar to your machine. Someone must have put a stitch regulator on it, as they didn't come with them originally.
Why don't you ditch the panto and try some FMQ on it, as big as you want? That machine is great at FMQ. I've used mine to quilt big quilts, before I bought a Juki longarm.
Have fun! It's a great machine.
*editing to add: My advice assumes your machine is not in a frame. If it is, then yes you are limited to the length of the throat. I don't believe I would use that machine in a frame....
