I think you need to log with less parameters, you can drop most the mapped points, it looks like 6->9 are the ones used during that pull if you want to keep a few. It looks like you're hitting comb. stab. limit and then turbo FMEM at 4500-4900 rmps, you can see your torque drop about 20 ft/lbs and the throttle start to close. Before that your throttle source is still 'TQ Red. < Driver Demand', which means your hitting some limit. If you can do a log with every 'source' logged, throttle position, and fewer extra parameters so there is better resolution on the sources and throttle it might help you narrow down where to look for the issue.
