Rather than bury this on page 28 I thought I would throw it out there for folks running big turbo's with DB2 mechanical injection.
I did find a aneroid setup for Ford IDI DB2's and it may work on a 6.5/6.2. An aneroid limits fuel delivery until the turbo generates enough boost to burn it thus limiting black smoke. The throttle on a DB2 is an RPM request not a direct fuel control. So even with careful throttle work you can smoke black as the DB2 governor can request full fuel for a small (throttle) RPM increase request. This device would limit the metering valve max opening until boost allows it to go full open.
For reference only as these do not yet fit a 6.5.
