Truck misses around 1500-1600 rpm on the high side when heavy. Once you pass 1600 goes back to normal and can drive at 1600 rpm no problem just gives you trouble when trying to get up to speed.
No check engine lights or faults. ( have a Motive device which will tell me if theres a fault )

Most likely injector
Big Road Skateboard Thanks this. -
I would agree it's likely an injector. I like to run return fuel into a clean 5 gal bucket and look for aeration. I've seen loose injectors cause similiar symptoms.
Will it miss if you just throttle up under no load? -

Unplug your injector connectors one by one until the miss doesn't change, then you have found your faulty injector.
