Thanks for the reply Skinny Pedal. If KPA is referring to the Manifold Absolute Pressure, is at 2.41. I have the timing set at 6 deg. adv. If you have TunerPro, I can PM you the BIN that I'm running. I posted a short data log on youtube, https://www.youtube.com/watch?v=YvRq...ature=youtu.be and a screen shot below.

1987 C-4, your car doesn't use a MAP sensor, so that value is a best guess by the ECM based on airflow.
You need to adjust the MAF tables in order to correct fueling. I'm not real familiar with MAF based systems so I can't really give you any solid pointers on where to start with that.
The man who says something is impossible, is usually interrupted by the man doing it.
The first place to check is injector constants and corrections. Ensure the fuel delivery at the current pressure matches the values in the calibration.
