I have a 94 F250 XLT 4X4 Extended Cab 7.3 Turbo IDI. I have been reading up on it some, and know I have to replace the 2 inch downpipe with a 3 inch.(and all the way back) I also know how to increase the boost, via the threaded Wastegate control shaft. I even know that I have to max the fuel by turning a set screw/bolt all the way in, and then back it out a threads width... I just have not been able to find any info that shows me the location of the fuel flow set screw/bolt... Could someone please tell me where on the Injector Pump is it?
