mil eliminators kill the code...so i don't see how you'd have any issue passing...however pulling the battery is a different thing...i've failed a few times because of having to pull the battery out for one reason or another a day or two before emission testing...now if he does a full drive cycle before testing (if that's even what this is about) then it won't read the battery has been removed
