93 F350 7.3 IDI, i decided to check my volts on my FILP. They were at .64 so adjusted the bracket but i ran out of adjustment and could only reach .95 volts. Most articles say this needs to be at 1.1 - 1.2 volts but I’m maxed out and cannot get there. Do you have any advice.

I was able to loosen the small FIPL screws and make a little more adjustment. New readings are:
With the new voltage’s reading , my shift points went higher in the rpms before shifting. I am seeing at least 2000 rpms before it will shift from 1st to 2nd and 2nd to 3rd. What is a common rpm to be at when shifting?
On my setup for whatever reason, when I attempted to set the voltage to the factory settings, I got hard shifts at higher rpms. I personally didn’t like it so I turned my voltage back down to the .64 i started with. This brought my shift points back down to a reasonable rpm but I still had the hard shifts in every gear. I disconnected both my batteries, let it sit for 5-10 minutes then touched the positive and negative cables together to de energize all stored power. Once I put the cables back on and took off again the transmission shifted super nice and still at a reasonable rpm range.
I Can’t int really explain why when I tried to adjust the voltage to factory settings I got less than desirable results and I can’t explain why leaving the voltage so low is working smoothly. If you have input on this I’m all ears. Ultimately I hope this information is helpful to someone in a similar situation.
FILP sensors are notoriously flakey, especially aftermarket units. I've had the break in half while adjusting them. Ford recommends replacing them ever 50k miles, or something like that because of the diesel vibrations.
You can test them with a oscilloscope to look for dead-spots in the sweep.
Best option is to find a new motorcraft part and install it.
