Yes, you can change out your early DME and AFM for later parts. I did this with my former '84 because the engine had this wicked hestiation under hard acceleration. The swap was a simple "plug and play" operation and took about an hour.
You can use parts from an '85.5 to '87, and it just so happens I have an '87 parts car. The DME has an AutoThority chip.
PM me if you are interested...

Basically, Yes.
If you are going to change the chip, you might want to swap out the stock throttle cabel cam for a round "throttle response" cam.
With the stock throttle cam there is a significant "flat spot" or "dead zone" in the throttle plate movement. Switching to a round cam gives you a much more linear throttle.
