Thanks to this forum and JoeCar for the help with getting my tune dialed to pass. It was a bit of a pain to get all of the readiness test to work. There was an issue with the 2 bar map and the MAF that was causing the PCM to throw a code. I ended up swapping in the 1 bar MAP.

For those interested, here are the test results:

Test RPM %CO2 %02 HC (ppm) CO(%) NO (ppm)
15 mph 1517 14.1 .9 8 .03 33
25 mph 1442 14.2 .7 5 .01 26
