Steady speed surge

Guys I can't figure this out. A few weeks after tuning my F-150 5.0, I noticed a steady speed surge at cruise, with or without the cruise control. It is noticeable but barely. No codes, but when it does it I saw the timing fluctuating. In looking over the log, it appears to be dropping into torque control spark source. I'm also seeing where at steady cruise, it goes into optimum power at 45-50% TPS? Is something off here? I am wondering if maybe cam sensors are starting to go and/or pedal position sensor or throttle body? I'll attach the log, it is a little lengthy but if you look through steady cruise you can see the spark sources and timing appear (to me) to be all over the place.
Yes, I have tried the throttle position reset several times and it does not appear to do anything.

Trucks going into optimum power at cruise because the pedal reaches it's threshold. Use what ever values you'd like, mine are just good examples.

Do the same steps on your Fuel Enrichment Pedal as well in Power Enrich. You have a stock file, there's a lot left you can adjust.

Ok I?ll start there and see how that goes.
With that being said, is that contributing or causing the surge?

Yes. The op threshold is. The fuel threshold helps and is better for PE and OP. Cam angles, torque tables, airflow calculations, spark tables are all for hauling ass. You can't cruise in Optimum Power at a steady 1500 rpm.
