I would suggest the chip you are already considering. I added one to my 87 and found great gains.

I also bought a Bursch exhaust kit for my car and that gave me some great power as well.

Besides those, I haven't found much else to be beneficial. The intake is a joke and will only make your car sound fast!!!! My intake merely consists of a K&N filter in the stock box. Which is only $40 and a must for an upgrade!
