Unplugging the MAF will certainly limit the EGR, but the only sure way to disable it and ensure no leakby is to totally remove the whole crappy mess by installing a Weeks Elbow Kit or install a simple "Block off Plate" on the exhaust feed line to the EGR system.
See this thread:>
viewtopic.php?f=5&t=76576If you install a Weeks Elbow Kit and unplug and discard the EGR valve, EGR cooler, and FCV, there are free tunes available on this forum to disable the DTC's that will be set by unplugging the items.
