It doesn't have an exhaust brake. Turning the "tow/haul" on just changes the shift points in the trans and if you aren't going a certain speed, it will keep the converter unlocked and make it run higher RPM's.

It will also (depending on the tuner) tighten the veins on the VGT, cause higher boost which is harder for the engine to compress if you are not into the gas pedal. Thus slowing it down.
