When you are in the control room, right click on your CE (he's the hunky guy at the end of the compartment). You will then get his "view", which includes the gauges showing the engine RPMs.

You won't be able to change them by clicking on them, but as you lower your speed using your usual engine controls, you will see your RPMs drop.

Some people say you have to be down to 50rpms to be completely silent. This is probably true, but you also won't be moving fast enough to get out from under them.

I go with 90 rpms, go as deep as I can, and, once I have their noise fairly much behind me, slowly leave the area (that's the plan, anyway).

Standard advice is to steer so as to leave as little profile as possible. All things being equal, good advice. However, you will never be able to "turn tail" on a rapidly circling escort, nor can you show a narrow profile to 2-3 escorts. Far better to use your low speed to get out from under, then worry about turning tail.
