How are you using your chips?
So had the lid temp reading around 120-140c however somehow the pork has hit ~90c already but not planning on easting for another 2-2.5 hrs. What to do! Save my La Cuisine, you're my only hope (just closed the top vent fully for the moment)
I would take the meat off and wrap in foil, then return to the grill. That way it will retain its moisture bit still take of extra Smokey flavour.
I've had similar problems in the past and foil saved it.
Just took it off now, it only came up to 93c so should still be good, felt very very soft when moving. Double wrapped in foil and in the oven at 50c to keep it warm and will shred in about an hour. Slaw and sauce all made up, just the potatoes and corn to BBQ.
