Failed pork belly burnt ends

[hooked on smoke]

I tried making some pork belly burnt ends and could use some advice/educating.
I started with 1x1 size cubes.
Generous sprinkle of Honey Hog.
Into the smoker at 250 for, oops, I was away for 4 hours. I did spritz every 40ish minutes with apple juice.
Next I put the chunks in a foil pan with about 3 tbs of butter, brown sugar and BBQ sause. Covered with doubled up foil.
Back into the smoker for another hour.
Pulled, removed the foil and back into the smoker for 30 more minutes.
The fatty stuff was melty goodness but the actual meaty portions were hard and chewy.

My apologies for the extended post but dang it, I would really like to know how to make these turn out the way they are supposed to.

Best regards

This confuses me...

You could try starting with bigger pieces

Leaner pork belly is what worked for me. First two times I tried making them. By the time I rendered the fat. Them meat had dried out.

I don't make burnt ends with pork belly very often. Mostly just plain pork belly.
I braise them to render the fat and then finish on the grill or griddle for a little crisp.
