    if there is a visual NO, if its just a smog test and your a/f is on point then maybe. Im not a 100% sure, but your tuner will disable the egr and air and the computer will show them as off..this may or may not comeup when they can your computer.

    if the codes are deleted properly you will see no ses light & your emissions readiness tests will complete...thats not to say you'll pass a visual though

    i have no clue what your asking...again if the codes are deleted properly you will pass all the necessary obd2 testing...ive passed several cars with flying colors that otherwise wouldve failed.

    once again, if you properly delete the diag tests, it will pass the ODBII test

    depends which tuner you have, I use LS1edit and you just set the diagnostic test to "X" which means don't use. I'm sure other tuners are similar, but not sure what the details would be
