If the “flash didn’t take” you would have numerous faults active for wheel speed errors.

Cruising at 70 mph, what is your engine RPM and what gear does it maintain?
Cruising at 70 mph I’m in seventh gear at about 2800 RPMs

I've experienced this with a 2.0T that had very heavy 35's on it. It did not want to go into 8th on the highway under most conditions without being manually shifted into 8th. It just didn't have the torque available to maintain speed at the lower RPM in 8th gear with the added load of the big wheels and tires.
If your speedo was correct, the changes for the gear ratio setting took.

Ive never had issues with either the KO2 315s that came off or the new BBAT 37s that just went on to get into 8th gear. Do I need to go a little faster now to see 8th gear because of RPM and staying with 4.10s sure. But once I see the same RPM to make the shift as I did way back when I had the stock 33s it will hit 8th and stay there. I can run 80 all day long and stick in 8th gear.

If he's at 2800 RPM in 7th, he'd still be like 2k+ in 8th, which is enough to spin heavy 37s with beadlocks and 4.10s with my 2.0T, let alone his 35s and 4.88s. Something definitely not right if he can't upshift at those RPMs, and it's not low torque at those RPMs.
