Also, if the shop who did the diagnosis did not disable the hacks and scan with a fully Ford OBD2 Diesel compliant scan tool - the diagnosis is worse than useless.
If you do not have access to a Ford OBD2 Diesel compliant scan tool, and disable the chip and fooler hacks you are throwing blind darts.
Disable and completely disconnect ALL hacks!
Get a proper scan, make note of any DTCs and pending codes.
Killing the hacks may or may not clear some or all of the issues. Note that the PCM is running an adaptive strategy and will need to complete a full drive cycle after a PCM reset.
Scan again AFTER ALL THIS and if there is still an issue at least you will have tested from a clean and unadulterated slate.
My bet is the disabling of the hacks, and the PCM reset and relearn will at least give a clear path to follow - if not resolve the issue!

It's a ts 6 position chip. It hadn't had any problems before it was also taped in place so it wouldn't move. Maybe somehow dirt got between the connections or something and just made it go haywire. I'm going to leave it out a few days and drive it and see what happens.

Why does it happen? That's a great question and one I wish I knew. It could be the contacts are dirty or have oxidized, or it could be some sort of electrical anomaly. Either way pulling my expensive chip has proven positive for me.
99 people can have great luck with a performance enhancement, but if it doesn't work for you, it's all for nothing.
You can clean your contacts and reinstall the chip for testing, but if the issue returns, you'll have your answer. For me a solid truck is more important than the chip. Good luck!

Corrosion/tarnish on the contacts is "common as dirt". In my case, I borrowed a chip from a good friend who solders big globs on his PCM to get good contact on the chip (I learned this later). Unfortunately, this spread the contacts on the chip out, making a rather loose fit on my PCM with svelte tinning on the connector. I had to yank it 400 miles from home to get the truck to keep running - and my bigger sticks made for a touchy throttle on the drive home with stock calibrations in the PCM. I have since reflashed my PCM for stock power with the sticks.
Note: Never drive in bumper-to-bumper traffic with big sticks and stock tuning... at least not without a barf bag on-board.
