87 F 250 without original engine

I just bought an 87 F 250 that has had the original 351 w/carb replaced by a 351 EFI. Where should I start to investigate to make sure the engine is running as it should? It runs fine, but I think it might be a bit fuel starved. Even empty a slight grade will cause a downshift in the automatic tranny and require me to keep my foot in the throttle more than I think I should have to. Also, since the computer port is not inside the vehicle, any ideas where to look to hook up an analyzer?

What kind of analyzer?
Are you sure the other engine had a carb on it?
What transmission do you have?
Does it have OD and is that what it is shifting out of?

Look at the top line of this forum page and click on "tech info" and then click on OBD1 and you should get the info you need.
