Bought tune combo with DP through Mike-XPH for a total around $1000. Added spacer and no CEL so far. One thing I do before inspection is swap Cat (takes less than an hour) and pull out the tune and hide wires. No issues so far, car sounds good WOT, more burbles and sometime backfires (Loud). Well worth the once a year I need to pull take it apart while I'm under warranty IMO.

If your dealer does not allow mods, how did they not detect the tune. Even if you remove the box and wiring itself, it leaves remanence behind that is very obvious to anyone working on your car.
