Just reposting my observations. Everything works great as it should. The car is MUCH more powerful. However, the CEL (check engine light is back). I opened up the hood and made sure the MAF sensor wires were all secure/connected and they were. Nothing loose anywhere. I then proceeded to use ESYS to "Clear ALL DTCs" and then it went away...I turned off my car...waited a few minutes...turned it back on...the CEL returned. I then did the single Clear DTC option and this cleared it...turned off the car...turned it back on...CEL still there.

Hopefully, this corrects itself because the chip is working as it should with the factory RaceChip tune settings S1=B S2=1. I wonder what could be causing this. The CEL did not come up when I drove the first 20 minutes I got it installed.
