sending the ecu unit to the USA and back, any shipping or tax issues?

I assume ESS has a few versions, as I get the full SS step headers, race cats, x pipe and sport mufflers, they probably have another setup for mine?

Does this ESS software have some code that we input to turn on and off? like when we take the car to the dealer we can turn it off and it's non detectable?
