I tend to agree, but you can exchange everything, multiple times, but you can also use your brains, and do a test like I said.
Put a boost firmware in, and see if the motor starts revving higher then you are used too (it will already do so with just a few degrees of boost) then unplug the sensor wire and see what it does then, because then it should act as if it has 0 timing.
Then you know for sure the problem lies in the sensor circuit somewhere, and most likely on the ESC side.
So as I also already said, check the pins of the sensor connection on the ESC.
You can even put some pressure by pushing on the sensor cable with your finger on the ESC side, or hassle somewhat with the wire, while doing your test, and this should also give some result......
