91 F250 with 5.8

Truck is a little doggy for me. I was just wondering if they ever put mass air on the 5.8 in trucks or not. I gotta do something to up the power, this just aint gonna get it done. If the truck wasn't so clean and only 86,000 miles I would have never considered it but it is just way to clean for the price. I'll just carb it if I have to was just hoping they did mass air at some point, I would much rather do it that way. Any info appreciated.

For my 5.8 I grabbed a 5.0 mass harness and computer then chipped it with a quarterhorse. I had some modifictions to the harness (tranny Plug mainly). After figuring out power and grounds I was all set. You could go with a new harness from fordfuelinjection.com It really depends on what tranny you have.
