Scan master question

[jimmysgbody]

I have an 84 hot air I upgraded the coil ignition upgrade along with the 86 87 computer I read online and I found some contradictory information can I upgrade to a scan Master unit also could someone please explain to me what the scan Master would actually do or if I would get any benefit from it being that I do not have an intercooled engine

In hindsight I wish I would have got an intercooled one I'm just having a heck of a Time with the hot air set up
