'01 Excursion 4x4
I have a 1988 Ford F-250 Extended Cab 4X4 with a 6.9L and C6 automatic transmission. I put a 7.3L injector pump on it because I was told it would put a little extra pressure to my injectors, thus increasing my power and mpg (Junk yards will say anything to make a sale won't they?!?). I'm overfueling the engine now, and it blows out a lot of black smoke when I stand on the throttle or pull a grade. Is there a way to turn down the fuel rate on that 7.3L injector pump, or do I just need to go buy a 6.9L injector pump? This is my first diesel, but I am sure it won't be my last.
