Thanks. Which level B series did you start with?The M380 comes with a locked Access Port. That means you can not get a custom tune / load any other tunes on it. It is basically an off the shelf tune designed to work with all cars with the included Mountune parts. The B packages come with a normal Access Port and include 45 days of e-tunes customized for your vehicle. It will have better performance than a generic tune. Also, you can go to any tuner of your choosing later down the road. I went the B route even though I live in Cali.
