P0101 error code

Got an error code on my truck P0101 mass or volume air flow circuit range/performance problem. I recently installed a URD MAF calibrator. my truck had some trouble starting up the first time but after that it was fine. definitely noticed a difference with the urd calibrator in noise and power. Drove my truck for a week or two and my engine light came on and read that code. I took off my maf sensor and it was dirty so i cleaned it, not knowing you arent supposed to touch it. reinstalled it and my truck wouldnt run, so i replaced the maf sensor and the light went off and it started, after 2 drives the light was back on. Not sure what the problem is or how to find the problem and fix it. Idk if my truck is rejecting the urd chip or there is a problem with how i installed it. need help thanks!

 

Logical troubleshooting 1, 2, 3

IMO...

The truck ran fine without the Cal Chip, with no CEL Code.

Installed the Cal Chip, Runs fine, but throws CEL Code.

The calibrator chip is the problem. Remove it.

Sorry, That is the best I can do on the web.
