My local dealer tells me that if i get a tune from a local tuner (and they have a tuning rep right at the dealer), if anything happens I'll be covered. Is there any truth to this?
Is JB4 a safer option? Normally I'm not a fan of piggybacks, but i don't want to lose the warranty.
Is there an option to buy a different ECU, swap it in, and if anything happens to swap in the stock one?

JB4 is catchable now. My old 320i was flagged and it only had a JB4.
