I actually stole this tip from Charles Ledger :) but have been using it for the last couple of weeks with very definitive results.

Using a rubber band and a latex glove, attach the glove to the de-gas bottle. with IDS or similar tool set idle to 1100 and command the VGT DC from 10% to 85 %

Here are the results of VGT DC @ 10%, very little pressure in the glove [2004 Ford F-450 Super Duty XL, Engine/Propulsion Photo]

Here are the results after about 5 seconds at 85% DC [2004 Ford F-450 Super Duty XL, Engine/Propulsion Photo]

There are a few other methods of determining a blown EGR cooler but this one is certainly the easiest.
