Nothing wrong, the scales are different on both sides of the chart. One for Torque, one for HP.

HP = Torque * RPM / 5252
So, both the blue lines and red lines must cross at 5252. So along the bottom, on that scale, at 5.252 (x1000)
That is, the "X" for both graph lines should be vertically one above the other. Instead, it looks like one crosses at 4900+, and the other at the correct value.
My suspicion is that the blue line was artificially lowered, straight down, to make the graph look better. Regardless of the reason, that first graph is not possible.
The second one that failsaf3 posted is much more reality-compliant.

Actually the torque and HP lines ONLY cross on dynojet dynos which correct both HP and torque. SAE mandates you correct only HP which means that on my Dynapack dyno we rarely see the lines cross at 5250. Only if by coincidence. To correct both creates some inacuracy. We use SAE rules, unlike Dynojet.

Good to see you again, just been buried under a new job, new house, band that's taking over the world, etc...
