will this help me pass inspection?
No you will not pass due to the fact that you reset all of your readiness test status bits when you delete a code or re-flash your VCM. It is implemented this way to keep people from having a car with defective emmission equipment and going by autozone and deleting their codes on the way to the testing station.
Here is a post that I wrote that may explain what readiness test are.
