Food for thought, I live in Buffalo, NY and my dealer doesn't allow any mods. I'm still under warranty on my 18' m240i and I'm running BMS CAI, VRSF cat less DP with JB4 tune. 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.

The JB4 is plug and play, all I do is disconnect the battery, unplug the harness and disconnect the OBD cabling to the controller tuck it away. I have only needed to take it in for normal maintenance (ie. oil change, inspection..)

Correct, but ecu stores data like max boost correct? I have heard that even piggybacks show obvious signs when uninstalled. At that point why wouldn't you go with a flash tune if they're both voiding warranties?
