What's involved and what can I expect for my '87? Who's chip is the best performance option? Right now I'm replacing all the ignition wires, plugs, rotor, cap, etc. That in itself made a world of difference.

 

Quite honestly I wouldn't even bother. You are looking at about 10hp max, no matter what they say. I have dyno'd chips that were suppose to make 15-20, and they made 1. On an NA car, it just isn't worth it. Put your money towards maintenance items instead.
