I had timing set to 'low' don't know how many degrees that is from tbe top of my head now, I think 5?
But are you sure it's looking good? I mean 48C at 17C ambient with a big fan on it and no hard driving is not that good or?
Almost 70C for the ESC also looks too high. Somebody on the offroad-cult forum said he had good results with removing the silicone stuff and the fabric and replacing it with this:

Edit: Regarding the glitching: I have seen that on the XL2 too, but it was glitching in forward direction. Also something is weird with the ms values, it shows min 0.500 and max 2.500 sometimes, although your calibrated endpoints are around 1.000 and 2.000. Maybe an optical insulation thing like Vedder suggested for the VESC would help?
