Surging???

So I have been noticing since I bought my truck from time to time when you hammer on it from low speeds through the acceleration there is a jump/surge...and not the shift point but a surge in the acceleration. This past weekend I towed a 38ft boat to Destin, FL and had the exhaust brake and tow-hual on almost the whole time which I thought it was but also had it happen once or twice with them off?? Any ideas or any of y'all experience the same thing?

Mine does the same thing just like a very small surge. I have been paying attention to when mine does it though and seems to be linked to a passive regen starting. So im not too worried about it. Maybe yours is something different though i bet its the same though. Casue it did it once today on the way home and i noticed and smelt a regen. Never does it when its not regening
