You can set your smoker to 225 but you still have no idea what temperature it is inside the chamber. There are many variables (improperly calibrated internal probe, soot on the probe, location of protein in relation to the heat source, outside air temp, breeze, etc.) so forget about what temp your smoker is telling you. Put a remote probe in it and note the difference. On my 1150, I set it at 240 and my temp in the center is 225. All smokers are different. You may have set your smoker at 225 and it was actually 210 in the center of chamber. So it's gonna take a while to get meat to an internal temperature of 203 when your smoker temp is actually 210.
I grew up staying up all night tending the fire to hold temp on our offset smoker. These pellet smokers make things 1000 times easier but there is still work to be done. No question wrapping the meat at the stall will speed things up. Hit 160-165, wrap in foil and wait until 201-203 and you'll be good. If you want to tighten up the bark just pull the foil and leave it on for another 30 minutes.
I have a 6 probe remote thermometer. About $50 on AMZ. One probe stays in the chamber to measure ambient temp. Each hunk of meat gets 2. Considering the prices at the butcher these days, it's well worth the $50. It has an app where I can set parameters. I set a max alert temp at 300 (in case it catches on fire) and a min alert for 150 (in case I run out of fuel or the power goes out). It'll wake me if things get weird overnight. Highly recommend for long cooks.
We've come a long ways since my days growing up in South Carolina. Here I am 50 years later sleeping while my smoker holds temp. What a life...
