Custom Tune and Emissions?

[NCBuzzard]

This may be a dumb question....Im getting ready to order me a custom tune but was wondering if it will still pass emissions test? where i live they hook up a computer to your port in your truck to do the test. i just didnt know if the custom tuned unit out for some reason not let me pass. thanks...

A tune shouldn't make you fail an emission's test,unless you had them turn off your cat's or similar.
Make sure to let the tuner know your state and that you need to pass emission's.
Of course it all depend's on who tune's it also.
