I noted some significant spikes between 5500 and 6000 RPMs, at the torque sensor and injector DC. I circled the the spikes at the torque sensors in the picture below, however you can see it also follows the injector duty cycle pretty closely. There is a spike in the airmass, but doesn't follow the spikes perfectly.
Could this just be external factors like hitting bumps? I included a video of the actual pull, but it looks bumpy all around.
