Breaking my virginity on this forum and thread...
I didn't find anything in the search under this thread, so IDK if it's been discussed elsewhere, but I was wondering if CarMax's extended warranty would have any effect when using an MHD tune?
As an FYI, it's a 2013 135i W/43,000 on the clock; bought 03/31/22.
