It's a bit confusing, I looked into it a bit. The Amtrak portion (Porter to Kalamazoo) was upgraded to 110mph back in 2012 and has been running at that speed in regular service.
The state-owned portion (Kalamazoo to Dearborn) is slated for 110mph service eventually and the PTC was put in place to support this goal, but the track is still a limiting factor (and probably curves, bridges, etc). This line will be upgraded to 110mph speeds one section at a time but funding and progress is slow and I haven't seen an estimated completion date.
