Seems as though it's running pretty good now. With those stock heads, and base, you're not getting the full ben. of the cam, and runners. I''d hook a scanner up and see where things are in regards to running rich or lean. If you are running OK in that deparment I'd just wait on the chip until you do heads, and base. That will increase your air flow a good bit, and then you will most likely need a chip. Plus the MAF system is much more forgiving.

Like said, you need to hook up a scanner to see what the ECM is seeing. This is not the best, but it is a start. You will want to take a look at your BLM numbers. These are your long term learn numbers. If they are far from 128, you could use a PROM. Will it be a major kick in the pants,... not until you do the heads/intake.
You know somebody w/ a scanner?
