should be able to... IIRC my 3100 with 19lb/hr injectors had a 75% duty cycle around 4000-4200 running on the old PCM...

Can you say fish tail at every takeoff? It sounds like Roberts inlaws has the 3.45 gears or worse in the rear. My gas mileage hasn't changed since the 3.73's and the last time I checked (over a year ago) it was around the 21-24 range which tells me Ford did a really bad job trying to put gears in there that matched the truck/engine combo.
