Back pressure sensor mod
I have an e99 7.3 and have heard you guys mention the exhaust back pressure sensor mod and I would like to know how to do it and what all I need to do.

Some people wire it shut and gut the valve in the pedestal. Some would change the pedestal to a non valved unit.

To gut the pedestal, simply unscrew the catch from the end of the shaft, pull the snap ring out of the pedestal on the opposite side, then tap the shaft. The whole thing will come out. Then get a 1/4" NPT tap and plug. Tap the hole in the pedestal, remove all shavings, install 1/4" plug with some teflon tape to keep it from leaking, and reinstall cap with snap ring on other side. Done.
While you have it all off, tighten up the wastegate rod as well. Put a few turns on it and you should be good...
Here's what mine looked like after the above work:
