Not every one thrus a code for the EGR delete, so you don't necessarily have to get one. Mine never thru a code, much less caused the light to come on. I've known a couple of 04 trucks to do the same. However, if it does throw the light then you will need to turn it off.
It's going to be hard finding an x2 anymore, that would be the one that I would actually get as that seems to have less issues then the x3(although issues are minimal, just more of a frustation then anything from what I remember). x3's I think are all custom tuners now, I don't think they have any that have canned tunes unless you use ebay or something like that and managed to get the older 3015 part numbers, if you buy new I think they are all blank and ready for custom tunes, if not you can convert them(all except the ones that just do 1 tune, like the economy one etc).
