i have a 1993 f700 with 5.9 cummins and 5 speed with 2 speed axle i am looking to add power for towing to it.

I was looking at starting simple with a 3000 governor spring kit and a 5" turbo back exhaust.

im not sure if i should throw a afc spring kit and a fuel plate in there or not.

 

You can make your own fuel plate, a #0 or 100 will do it, since it will want more bottom end grunt anyway. An AFC kit isnt really necessary.
