25mph can't be right. I don't know if I ever hit 40mph with my 8XL, but it was very fast and my truck was heavy and I was only using 14 cells.

That 9920 might be bad as you pointed out. If you were running on fewer FETs due to some being burnt out, that could cause the heat and reduced performance. Too bad you didn't know anyone that lived near you who would let you try another ESC.

Are your batteries up to the task? That 8XL can pull some current. If they can't supply the current required, the truck will be slower and also cause the ESC to heat up. When I first put my V1 Revo together, I used less-than-high quality cells (just to try it out) and there was definitely a performance difference when switching to GP cells.
