Chassis dyno graph

It’s a superflow, Dual eddy flow? My guess that is load cell. I don’t know the flash rpm. It’s got to be over 3400-3500 rpm. So the peak might be influenced by the flash rpm. Honestly I have tried to see what it just stalls at and no matter how much brake pressure I apply it will start to spin the tire I could put a bigger tire on it. I’m sure I could tighten up the rear brakes, but never bothered. 343 hp. I have zero experience with dyno graphs, The graph just looks straight no curve. Sorry, I have no idea in which mode it was done.
