Yes you will need a tune.
Even bone stock, it would probably benefit from that, since whatever factory tune you have was for 198x fuel, altitude from sea-level to 14,000', weather from so FL to MN to AZ to WA but you probably don't cover near all those places, etc. etc. etc.
Visit the PROM board on this site; or, consider one of the aftermarket systems; or, consider a modern stock PCM such as a 0411.
