The tune itself won't make a difference for passing emissions, unless you are using it to disable DTCs, particularly those related to the Rear O2 sensor, which would only be done if you had already removed your cats(i.e your odds of passing emissions were iffy to begin with). Disabling those DTC causes the readiness tests for heated catalyst to show as "Not Supported", which depending on the state and/or specific inspector they may fail you.
In which case you can re-enable the DTCs in UpRev software and put your cats back on, or use an anti-fouler to trick the O2(many test pipes have this sort of thing built in), though occasionally this can still trigger a check engine light.
