Sputter problem

Ok so I finally get to drive my bronco for more than 20 minutes in the two years I have owned it. It is an 89 351w with a C6. When I am driving at about 55 it feels like it tries to load up and will backfire a few times. If I let off the gas it will go back to normal, and if I floor it, it runs like a bat out of hell hitting over 4 grand before shifting. Im thinking I must have a vacuum leak somewhere, or maybe even a problem with the fuel pressure regulator. What do you guys think, any suggestions?

Have you pulled codes yet? My Bronco was doing the same thing and it threw a code 211 PIP circuit failure. Replaced the PIP in the distributor and it runs great now.

How old is the fuel in it?

New fuel, new tank, both pumps and new filter.
