Default slow windows after outer door seal install

I finally got my new outer door seal for the passenger window on my car. I found that the bump stops you loosen for the install did not want to go back as far/as tight as the previous adjustment. I put it as close to the old adjustment as I could and snugged it down.

Now the window moves slower and won't go all the way up unless the door is open. I understand that the new seal will create more drag because it's new and will eventually break in and likely be easier on the window motor a bit later. Do you think the bump stop should be loosened up a bit to help free this up, or is it a matter of just waiting for it to break in? Thanks for any advice. I've never done this before.

PS- It's ok, but the fit of the Mid America seal does not seem to be as tight against the door as the original GM. There is a little gap between the top of the door and the bottom of the seal. Anyone else find this to be true of the aftermarket stripping?

After installing a new outer seal, my ribbon broke.

Take your door panel off and adjust the felt pads again.

It sounds like your window is pushing into the rubber on the b-pillar. Push the rear felt pad outward, and give it some more slack in front. You can also adjust the window so it goes up a little forward of the b pillar, and straightens out when it hits the limit stop.

One of mine does this now. It doesn't touch the b pillar when its part way up.
