Provided it's running and not showing any signs of knock etc I'd run it up, get to around 3000rpm and throttle at 50% and apply load with dyno. Do this for a time then return to idle to give engine components time to cool, then repeat at about 75% throttle 3000rpm and load from dyno to hold it there.
Let it cool etc, swap out fluids and then look into your tuning issues.
Of course this is the procedure I use. But if anyone has issue with it such as your tuner or engine builder, then I'd apply the logic they want to see for bedding the rings in.

The top ring was gapped too .017 and bottom ring was gapped to .019 ( CP pistons )
Is there any way I would be able to do such breaking in on the road instead ? I know it would be a lot easier on a dyno but I kinda wanted to save the dyno time for when the tuner is actually flown in.
Thank you again for such detailed explanations,
Again I do truly appreciate it greatly
