I've installed several Vortek kits in Weihrauchs but never a TX. The Vortek seals in the Weihrauchs start off very tight initially and after a day or two of shooting conform to the bore. It's not unusual to pick up 40 or 50 fps from the initial shots. I'd shoot it a bit and see if it comes around. If it doesn't I'd call Tom at Vortek about it. IIRC there's something with the TXs about different length something or other that requires the correct kit. Something sounds seriously off. Is there gun significantly easier to cock than before? Was there very little preload upon reassembly? I'm sure you'll get it squared away. Tom will be helpful and take care of you if it's on his end.
How tight was the new moly impregnated seal in the compression tube? If the new spring is doing its job it's possible or even likely the piston seal is too tight which will slow the piston travel down resulting in a lower velocity for the pellet. Turning the moly seal down is not recommended so you may wish to try the results with your new Vortek kit and your old piston seal.
If you're trying to get more power out of your TX 200 with a stronger spring I strongly recommend having a new cocking shoe on hand.

As for the Vortek seal, I've read the same in some other places - I'm hoping that it will break in after 400-500 cycles and pick up some fps. The gun seems to cock about the same - definitely not easier than before. The preload was a little less than before but not significantly - still had to use a spring compressor for re-assembly. What is true is that the spring wire in the Vortek kit is narrower than the stock spring wire (.122 inches vs. .128 inches). I spoke to Tom @ Vortek about it and according to tom, the type of wire and winding in the PG4 kit makes it perform just as well or better than the stock. I have emailed Tom a couple time about this issue but haven't heard back yet. I may just call him - might be too busy to read all his emails.

The seal may have been a bit tighter than the old seal. I like your idea of putting back the old seal and seeing what it does - I'll give it a shot and post what I find.
