Mass Air Conversion on '92 5.8L for my F-250?

[Vandal_89]

My '92 F-250 has a 5.8 with a 5 Spd. I was hoping to convert to mass air so I could change the cam and increase the injector size. What I am looking for is better low end torque and greater horsepower. I was thinking that mass air might just be the ticket. The truck is mainly used to tow my Snowmobiles, ATVs, and miscellaneous trailers such as my ~8000 RV. But I also use it alot in the fall foing off-road getting to out of the way elk & deer hunting locations (usually through mud and snow).

I know with my '87 mustang I was getting like 18 mpg and when I put header, off-road h-pipe, changed injectors to 24 lbs and went to Mass air i got almost 22 mpg. My pickup get 12 mpg now.... and towing my ~8000 lb trailer it gets like 8 mpg.

I'm assuming that the A9L conversion will use the same wiring harness and wiring pin change for a mustang Mass Air Conversion When did my mustang conversion I thing the most expensive parts were the computer and MAF.
