I'm speaking of this one.

Edit - Burger seems to think I may have a bad module and offered to send me another one to try. I've chosen to get a refund instead.

So I have a 2014 X1 28i CPO and I was thinking about installing one of these for more power but a tech at BMW said even after you remove the tuner they can still see the piggy back on the logs and the tuners void your warranty. How are you deleting the logs?

ehh nvm, i think i found my answer here http://f80.bimmerpost.com/forums/sho....php?t=1142408
