Not if you do anything requiring a tune, which will be required with the Ecoboost and with a lot of mods on the 5.0.
*cough* separate ECU *cough*
*cough* reflash to stock *cough*
Thats how they do it for the Genesis. I can either send in my ecu (stupid, would have downtime while waiting to get it back), or buy a spare and have it programmed to my vin with the tune on it.
Not that thats optimal as itll run you an extra $500 on top of an already rediculous cost (like $300) to tune, but its not difficult to swap out an ecu. Also guys with gens do it because people have lost tunes by getting a simple oil change and the tech checking and reflashing to the latest hyundai tune.
Ill likely wait until there is a better alternative, like a handheld that lets me use it as an interface to do my own tunes so I can just reflash to stock before driving to the dealer for whatever needs to be done. Also considering that while under warranty id not go past intake/exhaust, I can just throw the stock intake in and make it all look stock.
