My z28 is having some backfiring issues, I have access to test it. It isn't throwing any codes but i wanna see if all the values and such match up or if there is anything abmnormal. Anywhere i can find what everything should be reading when at idle or driving?

If you put your scanned numbers on here we can break them down and see if anything is off.
