I'm gonna check out that other tune that you mentioned.
You don't have to disconnect MAF sensors. I believe this car doesn't even have those, that was for previous gen N63tu Jb4, not our N63tu2.

As far as tune goes, it works fine for me, no issues so far. With the Bluetooth kit it's pretty convenient too. You can turn off the tune any time. I run dme flash as a backend flash and Jb4 on top.

Terry is super responsive over email, if you have any issues with Jb4 just ask him directly.
