"Unless they swapped in an injection pump off a 617 turbo, it's not doing a thing but pumping in some extra air"
Not neccessarily.... While I am not entirely familiar with the inline Bosch pumps it is possible to turn up/increase the fuel delivery on most pumps fairly easily. This may have been done by the intaller or previous owner. I have turned up a Bosch VE rotary which is simple, there is an external adjustment and also on a Stanadyne DB2. The Stanadyne was more difficult requiring opening the pump up and finding the correct screw but performed while on the vehicle. Performing a mod like this is a calculated risk as the fuel is increased across the entire rpm range regardless of load. Believe it on not many diesels do without ALDA's, simply relying on the pre-programmed fuel curve for enrichment. This is where an EGT gauge is very helpfull. When you start messing with mods over stock fuel settings, bolting on turbos, increasing boost, etc. then you better know whats happening inside the motor. BTW, Mapleleaf, put 4-5 people in the car and run it up a long grade at highway speeds. That will give you a much better idea of the max sustained EGT's than quick 0-60 type sprints. RT
