1986 Custom Deluxe computer?? Smog equipment???

[Hart_Rod]

I just bought a one owner rust free 86 SWB with 93K (305/700R4). Its a very clean truck that I don't plan on doing much to other than fixing a few small things:

heater core is leaking, replaced the temp sender, the seat needs recovered on the drivers side, I picked up a tilt for it, , had dual 50 series flowmasters exhaust put on it, I may drop it a little later on.....

One thing I have noticed about it is that it has a lot of smog stuff on it and it appears that it has a computer behind the glove box. Is the carb computer controlled? Is there a way to tune the computer? Can the smog stuff be eliminated? Should I just leave it alone and drive it? Thanks for the input.
