My best guess is that being bolted to the firewall weakens the magnetic field.

My first guess would be a low supply voltage.
Is the supply voltage still around 5v when it is in the truck?
Maybe try using an independent supply voltage to test it when it is bolted in position.
Or try taking it off the firewall but still connected to vehicle supply to see if the mounting position is the cause.
The cable allows the throttle arm to move all the way to the physical stop?
Could the wiring changes to the controller still have a series resistor in the supply circuit or something like that that allows the supply to test as 5v unconnected but when connected to the pot box it doesn't deliver full 5v?
