When do the engine RPMs bounce when driving?

It seems to happen primarily when traveling between 45-55mph. When driving, slightly accerating, the truck is doing about 1100 rpm in its 6th gear. The engines RPMs seem to bounce back and forth 50-100 rpm. It is not the usual ‘bounce’ you get from v4 to v8 mode, it is happening while accelerating which i can see is keeping it in v8 mode.
