Which flash tune?
So, I recently bought a 2017 m240i coupe (pics to come soon in a WIP "check me out" thread). This is my first BMW and I LOVE it. Ever since I bought it, my free time has been spent researching and reading countless posts on this forum about different modifications, owner experiences, etc. During this process, I came across piggyback tunes, which I don't want to do, and the flash tunes. After reading, I found that there are 3 current flashes (available/available soon) that interest me a lot. Since I'm new to this, I am wondering what are the general thoughts on MG, BM3, and MHD as far as quality, service, and reputation go. I know there are other flashes such as Mission, which I will have do my transmission tune, but I like the ability to change my tune at a whim, should I desire to.
